Fraunhofer FEP works on cost-effective system solutions for flexible devices and presents results at Plastic Electronics 2014
A significant growth is predicted for the market of flexible devices. The topic “Wearables”, namely intelligent, wearable systems with several useful and funny features is currently one of the major discussion topics. To enjoy more comfort, exceptional designs and higher functionality manufacturers and users ask for flexible electronic devices, like displays, lighting elements or circuit boards.
Although research and development groups have already made considerable progress in this field, not all challenges could be solved so far. Various topics are subject to further development, e.g. materials, processes, machines as well as system integration.
Fraunhofer FEP provides a roll-to-roll process line which enables the application of organic materials for OLED (organic light-emitting diodes), OPD (organic photodiodes) or OPV (organic photovoltaic) on flexible substrates in one complete technology. The process includes the structuring, automatic inspection of the initial substrates, the vapor deposition of the organics and, finally, the encapsulation of the coated films or glasses.
Organic electronics certainly require flexible electrical contacts. Therefore, Fraunhofer FEP implemented an additional printing process of metal contacts for the reliable contacting of, for example, large-area flexible OLED on metal, polymer and thin glass substrates. In cooperation with printing paste manufacturers and other suppliers, e.g. machine manufacturers, adhesive manufacturers, encapsulation film suppliers, the scientists are now able to develop optimized products for required process steps under production conditions.
Dr. Jacqueline Brückner, Project Manager Surface Analysis for the roll-to-roll organic technology, says: “Our customers have different requirements to design and mechanical stability of devices. With our know-how and our process equipment we provide a unique development platform for all these demands.”
For example, there are various solutions for the device contacting. Currently, several contacting solutions with flat ribbon cable, like ACF (Anisotropic Conductive Film)-Bonding, ACA (Anisotropically Conductive Adhesive)-Bonding or ACP (Anisotropic Conductive Paste)-Bonding are evaluated.
Examples of different contacting solutions, special contacting and encapsulation layouts for the roll-to-roll OLED processes will be presented at the booth at Plastic Electronics 2014.
Beside this exhibition, Dr. Olaf Hild of Fraunhofer FEP will give a talk with the topic “Organic Electronics and Organic Photodiodes“ at Tech Arena 1, ALPEXPO on October 7th, 12:40 pm.
About Fraunhofer FEP:
Fraunhofer Institute for Electron Beam, Plasma Technology and COMEDD FEP works on innovative solutions in the fields of vacuum coating, surface treatment and processing with electrons and plasmas as well as organic semiconductors. The core competences electron-beam technology, sputtering and plasma-activated as well as PECVD high-rate coating, technologies for the organic electronic and IC/system design provide the basis for these activities.
Thus Fraunhofer FEP offers a wide range of possibilities for research, development and pilot fabrication, especially for the processing, sterilization, structuring and refining of surfaces as well as OLED microdisplays, organic and inorganic sensors, optical filters and flexible OLED lighting.
Our aim is to develop the innovation potential of the electron beam, plasma technology and organic electronic for new production processes and devices and to make it available for our customers.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
