Powering a Flexible world - Thin and printed power storage

Pritesh Hiralal
CEO
Zinergy UK Ltd.

Abstract
Zinergy turns the traditional alkaline battery into a thin (<0.5mm), flexible and low cost form by using printing technologies. In addition, its unique electrode design allow for better performance and rechargeability, in a completely safe and environmentally benign design. The last decade has shown a large development in the areas of flexible electronics and Internet of Things (IoT). New electronics and materials are permitting designers to produce a wide array of devices. Many new concepts are being tested, from ubiquitous sensors, to wearable devices. Some will succeed, some will fail, but the fundamental development behind these devices are around to stay. However, one particular area, the battery, has not developed as fast as the rest. The power source for these remains in the old traditional bulk form. As a result of strict packaging requirements, the battery still maintains the classical case form factor, and poses a design limitation for many design concepts. There is an urgent requirement for thin, flexible energy storage devices which can conform with different device sizes and shapes. Emerging topics such as wearable technology and IoT require some different parameters for the battery, such as ultra-thinness, small physical footprints, flexibility and light weight which are becoming increasingly prized. The classic zinc battery is by far the technology with the highest number of batteries shipped, principally due to its low cost. We translate this well known battery technology into a flexible, printed form factor, and add a few materials innovations to improve performance and improve on rechargeability, opening potential for a thin printed battery which can be produced at a low enough cost that make it suitable for high volume applications.

How flexible electronics will improve patient's daily life? SUBLIMED, end user point of view.

Nicolas Karst
CEO
SUBLIMED

Abstract
SUBLIMED develops a medical device, actiTENS, targeting the chronic pain market, which concerns 1.5 billion people worldwide. actiTENS is based on a proven non-drug therapy, transcutaneous electrical nerve stimulation (TENS). Conventional TENS devices take the shape of a voluminous casing (hand carried, attached to the belt or worn around the neck), tied with cutaneous electrodes through long cables causing physical and psychological embarrassment which highly compromises the adoption of the TENS by patients. actiTENS® offers a miniaturized, thin and flexible device, which is directly worn on the body adapting itself perfectly to the morphology of each patient. Easily hidden under clothes, wirelessly monitored by smartphone, actiTENS® discreetly supports patients in their daily activities. In order to better adress patient's needs in terms of discretion and ergonomics, the next generation of wearable medical devices should be as thin and as flexible as possible. Conventional electrical components (printed circuit boards, batteries...) do not fulfil end user requirements and therefore should be revolutionized. Through a concrete example, SUBLIMED will expose some of the end user needs in the field of wearable medical devices to turn conventional devices into Band-Aid like devices.

OLED for Automotive Applications: Status and Future Trends

Erwin Lang
Senior Key Expert OLED Technology
OSRAM OLED GmbH

Abstract
In the past few years substantial progress has been made in the development of organic light-emitting diodes for general illumination and for automobile applications. In this talk, the main drivers for OLED automotive lighting as well as its main differentiators from other automotive lighting solutions will be discussed. To take advantage of these differentiators, technology barriers for OLED need to be overcome. In this regard the requirement profile for automotive applications is compared to the requirements for general illumination. Rigid, glass-based OLED now meet entry level automotive reliability requirements and are entering the automotive market as tail lights in first series production vehicles. In the future, flexible OLED is expected to be the main differentiator for OLED in automotive applications, since the integration in 3D-shaped OLED modules enables completely new design possibilities for automotive lighting. We will highlight examples for innovative 3D-shaped OLED designs and present the recent progress on flexible OLED technology. Last but not least, the results of the latest development towards sophisticated 3D-OLED for tail lights will be discussed.

Abstract
IDTechEx has been tracking the progress in printed, organic, and flexible electronics since 2001. This presentation will give an overview of the key market segments which include flexible displays but also sensors and wearables. Since sensors typically have a much simpler structure than displays or logic circuits, the manufacturing learning curve can be less steep compared to other devices. In most cases, these sensors can also be made on plastic substrates, offering the advantages of mechanical flexibility, thinness and light weight. Recently, there has been a lot of interest in integrating electronics in textiles (e-textiles), where flexibility is essential.

Application of Flex Substrate in Subretinal Implant

Sandra Rudorf
Deputy Manager R&D
Retina Implant AG

Abstract
Some people suffer from blindness due to a hereditary disease, retinitis pigmentosa. It results in the gradual degeneration of the photoreceptor cells. The remaining retinal network, however, stays intact. In the case of the presented implant, the function of the degenerated photoreceptors is replaced by a microchip, consisting of a 2-dimensional array of photodiodes and electrodes. The subretinal implant resumes the same place as the degenerated photoreceptors. Hence, the remaining retinal network is employed for natural signal processing. Mounted on a carrier, the retinal chip is placed intra-ocularly. To provide the chip with energy, the chip carrier is connected to a subcutaneous supply unit. It contains a coil for inductive coupling to an external unit. All implant components have to be biocompatible. A further requirement of the chip carrier is flexibility, due to the implantation procedure and the curvature of the eye. Further-more, the chip carrier has to be long-term stable in a saline environment: a low water vapor permeability is essential as well as good adhesion of the carrier layers. The material of the presented chip carrier is polyimide with gold traces. The signal assignment is chosen such that neighboring potential differences are kept low. Additionally, intermediate conducting traces with high impedance are implemented, which significantly improves the long-term stability of the implant. Though polyimide represents a good barrier, conductive electrolyte solution from the human body permeates the metallic structures beneath the polyimide after a prolonged period of operation. This leads to the seemingly sudden failure of the implant in the patient. Hence, the topic of permanent implant functionality in clinical practice has to be addressed. Based on the international standard ISO 5841, the product failures observed during clinical use are analyzed statistically. The implemented procedure provides the cumulative survival rate as key figure.

Flexible Hybrid Electronics for Aerospace Applications

Benjamin Leever
Materials Engineer
Air Force Research Laboratory

Abstract
Flexible Hybrid Electronics (FHE) are expected to impact a range of aerospace applications including: wearable electronics and sensors for monitoring airman health/performance; conformal electronics and antennas for maximizing space efficiency and reducing aerodynamic drag; and inherently more durable circuits that will withstand the extreme strain, shock, and vibration environments typical of aerospace missions. The presentation will highlight our work in the development flexible devices as well as their integration with both rigid and flexible components through FHE packaging concepts. Our work includes the development of flexible and foldable lithium ion batteries based on carbon nanotube current collectors, which have been shown to be compatible with both roll-to-roll and direct-write fabrication approaches. We will show that these batteries offer the potential to significantly reduce electrode weight while maintaining equivalent electrochemical performance and dramatically improving mechanical resiliency. In addition, the presentation will discuss strategies for improving the survivability of electronics in high-shock environments. This work includes innovative packaging schemes for protecting traditional electronic components on PCBs such as encasing them in elastomers as well as investigating the deposition of flexible Si integrated circuits with stretchable interconnects on soft substrates. Finally, the presentation will detail our work in liquid gallium alloys for stretchable and reconfigurable electronics. Recent work has focused on aerosol jet and extrusion-based approaches for printing liquid gallium alloys as well as approaches to mitigate gallium oxide formation to improve opportunities for the development of reconfigurable antennas.

Innovative automotive door-handle based on R2R printing process, hybrid and heterogeneous integration

Jaime Herrán
Project manager
IK4-CIDETEC

Abstract
Aesthetics is one of the key factors that determine the evolution of the automotive sector, which need to correspond to visual appearance as well as to ergonomic functionality and utility features. Nowadays, the vehicle interior market demands both visual and functional renovation as well as its integrated electronic devices. Actually, the needs of the driver are covered by a technology based on mechatronic concepts, which has with limited functionality and makes difficult that the aesthetic evolves at the same pace as the market. Organic and Large Area Electronics (OLAE) is able to trigger innovation in different sectors, such as traditional industries (paper, plastic, printing and textile) to delivers novel cost-effective integration solutions to the traditional electronics sector. In this context, Roll-Out project (funded by H2020 TOLAE program, 2015-2017) is developing a new concept of automotive door-handle based on OLAE, which will enable enormous value addition to European Automotive industry without adding any significant extra cost. In particular, pressure sensors patented by IK4-CIDETEC (RTD partner), mostly based on interdigitated metal electrodes with several functional layers on top, have been scaled up to R2R process. The printing process has been developed by the Maxi Printed Intelligence R2R pilot line at VTT (RTD partner). The first functional prototype consists of a resistive sensor matrix formed by a 2x4 array with a tactile unit of 1 cm². After printing process and sensor assembled, resistors have been bonded by an automated pick-and-place system (hybrid integration). The final step is focused on heterogeneous integration by overmolding process. MAIER (End-User, TIER-1 automotive supplier partner) with the support of VTT has design and developed the new mold, according to automotive manufactures requirements. Different thermoplastics have been tested and injection parameters have also been optimized (pressure, temperature, speed, etc).

Large area printed piezosensors for wearable applications

Timo Grunemann
PhD student
Fraunhofer ISC

Abstract
Due to demographic changes the number of older employees, who want or have to work but are already physically limited, increases. At the same time the number of workers in medical care is insufficient to meet the demand as the society gets older. In consequence, there is strong interest in sensor technologies by employers and medical professionals in terms of safety-at-work and point of care technologies which can measure, support and guide the movement of body parts with simple-to-use techniques. Camera-based technologies however can be used at pre-defined locations, only, and, might cause difficulties regarding data protection. In this contribution, we present a sensor technology which can be integrated on textiles in order to measure movements of a human body by wearing a special shirt. At first, the sensors are designed to measure the bending and twisting of elbow and wrist joints. The technology is based on printable piezoelectric sensors realised by PVDF derivatives and PEDOT:PSS electrodes and processed by simple screen-printing techniques at low temperatures. The freedom to design the size and the shape of the sensors result in the feature that the sensors can be optimally tuned to the measuring task. Due to the fact that the sensors are designed as integrating large-area sensors, it is not necessary to position the sensors exactly. Printing the sensors on textiles instead of foils causes some difficulties in terms of quality and stability of the sensors. Measures to tackle that are pointed out. Technologies to realise a hybrid assembly technology and electronics for read-out of the sensor signals are sketched. Finally, measurements of bending signals, which are in the size of mVs and show linear characteristics, are discussed.

PI-Scale – a European pilot line for flexible OLEDs

Claudia Keibler
european project leader
Fraunhofer FEP

Abstract
PI-SCALE is a Horizon2020 project, which is an European collaboration to create an open access pilot line service offering world class capability in customised flexible organic light-emitting diodes (OLEDs) in order to accelerate the commercial adoption of this technology. The project brings together Europe’s experts and state-of-the-art infrastructure for flexible OLED fabrication, and enables companies to quickly and cost effectively test and scale up their flexible OLED lighting or signage concepts and bring them to a level where they are ready to be transferred to a mass production facility. Flexible OLEDs are ultra-thin (<0.2 mm), highly bendable, very lightweight, and even transparent energy efficient large area, patternable light sources. They can be made or cut to any shape or size, and can be integrated into formed components or seamlessly bonded onto curved surfaces. The commercialisation of this technology will open up a host of exciting design opportunities to create new value adding lighting and signage products in many different application areas such as architectural lighting, automotive, aerospace and consumer electronics. The pilot line is positioned to bridge the gap between R&D and mass production, and provides independent, open access services including: • Prototyping and pilot production of customised flexible OLED devices (up to 5000 m² of OLEDs/year) • Up-scaled materials, process and equipment testing • System-level integration of flexible OLEDs into products • Application-specific operational testing • Advice and “hands-on” workshops to introduce companies to flexible OLED technology

In order to evaluate the potential of printed devices for innovative system and drive technology accordingly to application requirements, 4 prototyping platforms have been set-up focusing efforts all-along the chain of skills. Focus will be given on the “Design platform for Circuit & System prototyping” enabling evaluation of technology upon flexible sensor systems requirements. For this purpose silicon methodologies have been adapted to provide a Design Kit available in Cadence Virtuoso format. It includes Sensor and N/P-type Organic Transistors compact models for DC and transient mode, as well as standard EDA tools (DRM, LVS, DRC). Characterization of fabricated analog and digital circuits is presented (logic gates, flip-flops, amplifiers, ADC, RFID circuits, multiplexing circuits, active matrix with embedded gate drivers). A focus on the expected functions for sensor interfacing and pertinent segmentation with silicon IC will be discussed. The talk will also illustrate how prototyping at system level drives the specifications on material development. The choice between PMOS and CMOS technology will be discussed regarding application and integration challenges. Simulation on relevant application case will also highlight performance requirements (reproducibility, current, speed, operation voltage). The impact for the choice of semiconductor and dielectric and the solution under study on the R&D platform for “Integration of Advanced materials” will be presented. Finally the challenges towards industrialization will be discussed with an overview on the tools and methods employed respectively on the “PICTIC printing Pilot line” dedicated to scale-up of printing process at GEN1 and on the “Characterization Platform and Reliability Lab” dedicated to evaluation of device performance, yield and ageing stability in order to support Technology Readiness scale-up (TRL4-7).

Organic Electronics: Photolithography or Printing?

Giles Lloyd
Senior Manager, Marketing
Merck

Abstract
Production processes for large area electronics are traditionally dominated by photolithography. This is obviously driven by the huge markets for displays and photovoltaics and hence significant investment has been made into the manufacturing infrastructure. For new technologies to gain any sort of foot hold in these markets, they will need to tap into this infrastructure and show compatibility. Printing is now emerging as a candidate for lower cost manufacturing with potential for greater customisation, particularly in digital printing. Recent activity in printed OLEDs for displays is an excellent example. For the transistors and by example, the backplanes of displays, there is also interest in both processes. Photolithography processes to enable access to the existing manufacturing infrastructure but also printing processes to ultimately realise the dream of fully printed roll-to-roll electronics that will drive the mega trends of ubiquitous electronics and the Internet of Things. In this paper we present formulation and process development for photolithography of OTFTs for integration in display application and fully printed OTFTs for Printed Electronics. The photolithography process includes optimised ink formulations and processes using standard commercially available photoresists, as used in FPD manufacture. This represents a clear step forward in compatibility with the existing manufacturing infrastructure and hence, is closer to real commercial production. The printing process includes optimised semiconductor and dielectric inks for gravure printing. All layers are developed for print performance, compatibility with previous layers (orthogonality, wetting etc.), and electronic performance. We present our latest data on development of both processes which clearly demonstrates that Merck materials are ready.

Previously we have presented a novel phosphorescent AMOLED display architecture that enables the fabrication of AMOLED displays using only two low resolution masking steps, and consumes comparable power, and has significantly improved lifetime, as compared to an equivalent RGB side-by-side AMOLED display using three high resolution patterning steps. This architecture can be designed to enable the mask resolution to be only half that of the resultant display in both x and y directions. This new architecture also increases sub-pixel aperture ratios by only requiring one emissive color layer change per pixel, and therefore only one mask tolerance per pixel. The increased fill factors further improve device lifetimes. Based in part on the architectures discussed above we will also disclose a new pixel layout which allows the user to selectively limit the amount of deep blue content in the display to mitigate the potential health issues associated with deep blue emission. In this talk we will present further advances on this topic including steps to increase display lifetime and a further modification to this architecture to render very high pixel resolutions necessary for virtual reality (VR) applications.

Applied Materials

Abstract
For the realization of next generation Ultra High Definition Televisions (UHD-TVs) both quantum dots (QDs) and organic light emitting diodes (OLEDs) will play a crucial role. Both materials are extremely sensitive to the presence of water vapor, so high grade barrier encapsulation films (down to 10-6 g/m2 day) are mandatory to achieve the 10 years lifetime at room temperature required by commercial products. In this paper the latest advances in R2R CVD processing will be illustrated, showing the impact on optical and barrier performance of substrate type, single layer and fully integrated multilayer CVD based film stacks. Architectural solutions to challenges inherent in moving from lab & pilot scale manufacturing to high volume production will be illustrated. Particular attention will be given to defect detection & mitigation, critical for achieving high production yields and enabling the upcoming wave of flexible electronic devices. Further developments will also be discussed in terms of infrastructure & process development for patterning of micron level features & devices.

Hybrid Integration for Plastic Film Electronics

Christof Landesberger
Manager Research Group “Thin Silicon”
Fraunhofer EMFT

Abstract
Polymer foils are an increasingly attractive substrate for several electronic applications. They are matchless for the fabrication of very thin and highly flexible electronic systems and rather inexpensive substrates for large-area applications. In combination with functional materials like the organic semiconductor and printing technologies there was big hope that electronic systems can be fabricated directly by coating and patterning steps without any assembly steps, a big vision for volume production of integrated systems. Despite the achievements obtained in this area, especially for photonic systems, there has been a considerable drawback regarding the realization of integrated circuits. Although there has been a lot of success in organic semiconductor research and related demonstration of applications, no realistic approach for a larger scale circuit integration is available that can compete by performance and economically with state-of-the-art silicon ICs. The difficulties in realization of organic integrated circuits lead to the concept of hybrid integration. In principle hybrid means bringing together the world of large-area coating, patterning and printing with the world of assembly and interconnect of components. On a first view, this is rather similar with the conventional approach of electronics packaging, however there are also large differences related to the plastic film substrate and the specifics of foil electronics. Dimensional instability, shrinkage and wrinkling, low temperature processing, bending and folding reliability play a much more pronounced role in plastic film technology. The different approaches for hybridisation on plastic films and corresponding challenges are discussed by means of different development examples from several application fields. In detail the impact of above mentioned critical properties are investigated application-oriented for packages of consumer goods.

A novel pick-and-place process for ultra-thin chips on flexible smart systems

Thomas Meissner
Head of Micro Assembly
Hahn-Schickard

Abstract
In order to truly make thin flexible systems smart the integration of ultra-thin Si-based chips is essential. This however requires the development of novel processes for the manufacturing and handling of such chips. Much progress has been made towards the reliable thinning of chip-wafers down to thicknesses of 20 µm. Nevertheless, picking the delicate chips from the adhesive foil used for wafer processing plus transportation without damaging and subsequently placing them on substrates remains challenging since conventional approaches for pick-and-place are unsuitable. Here we present a novel approach that relies on an optimized pick-and-place tool in combination with the use of thermo-release foils. We show that chips as thin as 20 µm can be quickly picked with little strain and hence be subsequently processed reliably.

Injection Molded Electronics: Mass Manufactured Smart Plastics

Antti Keränen
CTO
TactoTek

Abstract
TactoTek Injection Molded Electronics (IME) is a solution that integrates printed electronics (circuitry, sensors, and antennas) and discrete electronic components (LEDs, ICs, etc.) inside of 3D plastic structures, thus changing the 100 years old picture of electronics as “components in a box” into 3D smart plastic surfaces. TactoTek IME integrates building blocks of lighting, sensors and active control electronics to deliver a wide range of functions in high visual quality 2D and 3D plastic structures that are 2-4 mm thick. The TactoTek IME manufacturing process consists of five steps: 1) Print decoration on plastic film, 2) Print wiring, electrodes, antennas and other printable electronics on IML film, 3) Mount standard SMT electronics on film using standard 2D SMT, 4) Thermoform the assembled film into desired 3D form and 5) Use the assembled and formed film as an insert in standard injection molding process. Steps 1, 2, and 3 take place when the structure is 2 dimensional using existing high speed mass manufacturing equipment and processes. IME solutions reduce space and weight and simplify assembly while creating differentiating design opportunities. Some specific technology benefits worth highlighting include: using the plastic structure itself as a light guide instead of external assemblies, and placing sensors and antennas extremely close to part surface to improve signals and reduce noise.

Micro-Transfer-Printing for Flexible Passive Matrix Displays based on Inorganic LEDs

António José Trindade
Research Scientist
X-Celeprint, Limited

Abstract
Inorganic light-emitting diodes (iLEDs) are amongst the longest lived and most energy efficient light-emitters available for an extensive range of applications. Direct-emission displays using these types of light sources have been around as an established technology and are typically known as ‘Jumbotron’ displays. Recently, there is a growing interest in the miniaturization of such displays where pixels can be tightly packed (>30 per inch) in a multitude of substrates. To achieve the desired level of scale reduction, disruptive technologies are required to handle miniature wafer-fabricated components in high-density arrays and transfer these onto a new display substrate at high-speed, precision and low cost. Since control circuits, light emitters, sensors are usually sourced from different wafer-based material systems (Si, GaN, InP, GaAs…), this introduces added complications for integration onto display panels. Invented at the University of Illinois with over ten years of continuous development, micro-Transfer-Printing (µTP) effortlessly enables the heterogeneous integration of devices based from disparate material systems onto various substrates. By use of an elastomer stamp to release and transfer the devices arrays onto non-native substrates, µTP has a proven record in iLED displays, magnetic storage, Silicon Photonics, Photovoltaics and compound semiconductor integration. Here we present a display prototype using miniaturized iLEDs as fully functional pixel emitters. Standard transfer yields typically exceed 99.9% and the emitting pixels can be printed by a single print step (total of 3 prints for RGB displays). Due to the reduced emitter size (3x10µm2), displays have a high degree of transparency due to the low fill-factor that emitters and metal tracks occupy on the overall display area. µTP can therefore be a platform to fully functional rigid or flexible displays with high throughput, efficiency and reliability.

Continuous monitoring of manufacturing processes dedicated to PE

Michel POPOVIC
GENERAL MANAGER
IN-CORE Systèmes

Abstract
Continuous inspection is the key point to maintain yield targets and to ensure the repetitiveness in printed electronics manufacturing processes. Among the inspection techniques, the real time control based on visual inspection 2D and 3D is the most comprehensive solution. The multipurpose sensors (cameras) with adequate light source are used above all to run properly the process. The positions, overlap, registration of all printed/coated features are controlled with very high resolution. The process defect such as printing, coating defects which have the functionality impact on the elements (circuits, cells, sensors) are detected and localized to be removed in downstream process. This inspection solution offers also a huge flexibility which is essential for the processes which are in permanent modification toward the new ways and standards. The implementation of visual inspection into printing electronics process flows is demonstrated on two case studies: • circuit components from printing processes • organic photovoltaic manufactured in coating process. Image acquisition conditions are discussed as a function of used substrate and ink properties. It is shown for both examples that it is feasible to highlight crucial defects such as short circuits and circuit breaks, lack and excess of inks and inclusions of foreign particles and thus directly relate optical impact to electrical yield. “

In-line High Resolution 3D Surface Measurements for Substrate Characterization

Erik Novak
Director of Business Development
4D Technology

Abstract
As more flexible electronics products enter large-scale production, focus is increasingly moving from simply demonstrating technological capability towards higher yields, longer lifetimes, and superior performance. To improve profitability and market size of offerings, critical features that can affect performance must be monitored, including surface roughness, defect density, defect size and slope. Ideally, in-situ metrology can be employed in roll-to-roll equipment to allow real-time process control of these key parameters. Barrier film permeability, circuit performance, and overall yield may all be better controlled via real-time measurements from within the roll-to-roll processing equipment. This paper will present a compact, low-cost, large-field 3D metrology module for in-situ measurements of flexible electronic substrates. The module is capable of sub-nanometer vertical resolution and micrometer-scale lateral resolution for accurate roughness and defect height determination. More than 17 cm^2 per minute of surfaces can be measured with 2 um lateral resolution. Modules are very compact, slightly larger than a mobile phone, and can be arrayed to provide scalable areal coverage based on each customer’s specific needs. Modules are vacuum compatible, vibration-immune, and are unaffected by the film backside or roller characteristics and thus ideal for placement within coating machines. While primarily designed for metrology of flexible electronics substrates, particularly barrier films, this metrology system also can perform high-speed 3D characterization of glass panels, semiconductor wafers and other smooth surfaces. This paper will present data from a variety of samples measured these metrology modules, and correlate results with other precision measurement techniques. Flexible substrates will be measured on a roller in a roll-to-roll systems. Additional flat samples will be shown as measured with the metrology modules mounted over an XY stage.

The Unique Challenges of Designing Battery Powered Solutions for Flexible Electronics

Christine Ho
CEO
Imprint Energy, Inc.

Abstract
Powering the next generation of flexible electronics with batteries provides a unique subset challenges for battery designers. To enable the field, new materials, manufacturing processes, and characterization methods are needed. Furthermore, as flexible electronic devices become more integrated and compact, batteries become a more prominent focal point in the product design phase. Due to the latest exciting battery innovations, for the first time, product designers can think of batteries as a designable elements. This paradigm shift in product design requires battery designers to interact more directly with product designers to mutually understand what is possible, and what are key limitations. The challenges faced by battery and product designers in the flexible electronics space will be highlighted, and key strategies to overcome these challenges will be discussed. Today's ultrathin and flexible battery solutions will also be reviewed.

Lifetime Study of Flexible Encapsulated Organic Photovoltaic Modules: Optimization of Device Architecture and Selection of Encapsulation Materials

Solenn Berson
Head of laboratory of organic photovoltaic modules
CEA

Abstract
The lifetime of organic photovoltaic devices is a critical point limiting their marketability. In order to improve it, the devices rely on barrier encapsulation to prevent their oxidation by oxygen and moisture. A common technique is the lamination between two glued gas-barrier films. Water and oxygen ingress occurs as a result of the orthogonal permeation and the lateral permeation. In order to elaborate a suitable protection versus atmosphere, it appears important to be able to assess the complete encapsulation scheme. In this communication, we will describe the tools we have developed to characterize the encapsulation: gas barrier measurements methods allowing a rapid screening of gas barrier properties; and optical calcium test mimicking the real device geometry and allowing to measure the lateral permeation through adhesives and interfaces after lamination. This overall assessment of the encapsulation scheme helps to choose the material set, the encapsulation process, and the optimal geometry. A straightforward link between encapsulation materials characterization and device lifetime can be made and will be presented. However, encapsulation cannot account by itself for device lifetime. Further improvements in device lifetime can also be brought by optimization of device architecture. In particular, the interfaces within the device or between glue and device play a major role. We will show the influence of interfaces optimization on device ageing, along with mechanical and opto-electronic characterizations. Peeling tests coupled to physico-chemical characterization of the peeled devices are a powerful method to identify the weakest interfaces within the stack. As a conclusion, we demonstrate flexible encapsulated organic photovoltaics devices able to reach a T80 of at least 1000 h in damp heat conditions (85°C 85% RH) and after 200 thermal cycles (-40°C +85°C). Outdoor ageing were also tested.

Electrode and Electrolyte Ink Development for Printed Batteries

Michael Durstock
Chief, Soft Matter Materials
Air Force Research Lab

Abstract
Printable energy storage facilitates innovation in the manufacture of flexible electronics in that it will enable direct integration of a power source into a device during the fabrication process. To enable such advancement, we demonstrate a universal approach to develop free-standing and flexible electrodes for printable, high-performance Li-ion batteries. This simple approach utilizes a well-dispersed and directly castable mixture of active material, carbon nanofibers, and polymer to make printable electrode inks. The unique composite properties are mainly attributed to the formation of a 3D nanofiber network that acts as the conductive additive, embedded charge collector, and porous, structural scaffold to facilitate Li+ diffusion. Free-standing electrodes of three common Li-ion battery active materials (Li4Ti5O12, LiFePO4, LiCoO2) are prepared, each showing excellent cyclability and rate capability. To complement this component, we demonstrate a dry phase inversion technique representing a step toward controlled, printed porosity in Li-ion battery electrolytes. Our approach utilizes a solvent/weak non-solvent system to generate porosity within a polymer matrix and a ceramic Al2O3 filler to fine tune the pore size distribution to impart desirable tortuosity within the membrane. These electrolytes offer electrochemical performance on par with commercial separator films even at current rates as high as 5C, with better thermal stability and electrolyte wetting. This material can also be printed directly over an electrode layer without sacrificing performance in either layer. Additionally, the phase inversion process is applicable to composite electrode inks, yielding electrodes with increased electrochemical properties and better flexibility over those prepared with good solvent alone. This technology for both electrolyte and electrode inks is an enabling step toward direct integration of flexible power in confined areas or on non-planar device surfaces.

Organic photovoltaic (OPV) modules for the empower of autonomous indoor sensors

Noëlla Lemaitre
R&D Scentist
CEA

Abstract
The Internet of Things (IoT) is the network of physical objects—devices, vehicles, buildings and other items—embedded with electronics, software, sensors, and network connectivity that enables these objects to collect and exchange data. The number of applications in the fields of industrial and environmental monitoring, energy management, building and home automation is growing exponentially. The powering of all these objects is then a major concern, their autonomy is a requirement. The solutions to get these objects autonomous is closely linked to the energy harvesting from the surroundings. Organic photovoltaic (OPV) is one of this energy harvesting technology from light. This emerging technology offers numerous advantages, beginning with the ability to produce lightweight, flexible and coloured modules with an incomparable ease of processing. This technology with more than 10% efficiency and several years of lifetime is mature enough to be integrated into objects. Moreover, the possibility to use digital techniques (laser patterning, inkjet printing) allows the customization of OPV modules to the desired design for a successful integration. Their good module ratio at low light makes them good candidate for indoor applications. In the present work, we will present the results we obtained on inverted OPV modules with more than 5% efficiency, their behavior under low light conditions and different indoor light sources (white LED, fluo). We will demonstrate the ability of this technology to give the autonomy of indoor home automation sensors.

Polyester Films for the Next Generation of Flexible Electronics

Bill MacDonald
Business Research Associate
DuPont Teijin Films

Abstract
Recent Flexible Electronics advances have required material suppliers to deliver improved functionality to the device developers in broad applications such as electrophoretic displays, TFT backplanes, barrier films, photovoltaics, medical diagnostics, and sensors. The next generation of flexible electronics may require a different set of material specifications to enable flexible hybrid systems, foldable displays, and wearable devices. DuPont Teijin Films has supported this industry from the start with commercially available polyester film solutions that are both innovative and cost effective. These bi-axially oriented, semi-crystalline films provide the end users a unique combination of high stiffness, dimensional stability, optical transparency, solvent resistance, and low cost as compared to several other polymer film types. Demands on polyester film suppliers now typically include: smooth surfaces with low surface defects, low haze, near zero thermal shrinkage, low iridescence, UV stability, and the ability to tailor the surface chemistry to meet the end user’s requirements. This presentation will include an update on the latest clear, hazy, and white PET (polyethylene terephthalate) and PEN (polyethylene naphthalate) polyester film developments, while discussing the likely requirements and issues associated with meeting the film requirements for emerging applications. Past, present, and future PET / PEN polyester films can provide a balance of cost, processing temperature, and performance that enable cost effective solutions to the OEMs.

Constraints and possibilities for direct printing of stretchable electronics on thermoplastic polyurethanes

Eric Rubingh
Project manager
TNO

Abstract
Stretchable electronics have gained much interest in the industrial and academic world. Recent developments provide routes to integrate stretchable electronics on textiles and thermoplastic materials allowing applications in fabric and clothing (comfort electronics), formable plastics (formable electronics, 3D printing) and medical applications (skin patches, artificial muscles). The unique properties of thermoplastic polyurethanes (TPU), such as stretch- and ability to be laminated onto textiles will be shown and complemented by the unique stress/strain characteristics of the polymer. The talk explains constraints for direct printing of stretchable electronic pastes on TPU. Various stretchable pastes applied by screen printing of conductive structures in a flat-bed setup will be presented and our approach in compensating intrinsic shrink, strain-hardening and re-orientation of the polymeric chains upon printing will be discussed. Constraints are complemented by mechanical and electrical characterization will be provided, resulting in a stretchable electronics measurement protocol, including electrical properties under strain, conductivity loss upon stretching, cyclic tests, lamination and washability. The talk will be complemented by presenting the latest stretchable electronics demonstrators that are created at the Holst Centre.

Abstract
Flexible electronic become an integrate part of the internet of Things (IoT), by making smart system displays, sensors and active functional surfaces. Most of these printed devices are currently integrated on plastic foils, papers, and more recently on thin glass “foils”. Nevertheless, metallic foil appears to be a promising alternative for several raisons. First, metal can overcome important arising technological difficulties due to the shortcomings durability, moisture barrier properties (particularly for organic material) and heat dissipation. Moreover, metal will allow very original smart applications in Building, Appliance and Automotive. It makes possible a future generation of printed and low cost electronic devices in the metallurgy world. CRM group (previoulsy ArcelorMittal Research Laboratory) has developed a new advanced steel substrate dedicated to organic and more generally to flexible or conformable electronic devices. Metal will be flexible, rigid, or even formable devices. It will have very good oxygen and water barrier properties if properly used. It is an electrical and thermal conductor, which can greatly improve the lifetime of the device thanks to heat dissipation. Indeed, such substrates can be very helpful for integrated system in “extreme” environment (pressure, temperature conditions and so on). Moreover, smart steel systems can be manufactured in a roll to roll process, which is the key of a low cost, competitive process and compatible with flexible electronic manufacturing. During this presentation, smartsteel (/metal) applications will be outlined, dedicated to large area device integration. Special focus will be addressed on steel surface treatment to reach exigent physical properties (roughness, planarization, dielectric and conductive materials…) and low cost manufacturing process. At last, example of smart steel products will be presented, based on “printed circuit board “ and interconnected Back/Front side metal foils devices.
