FLEXIBILITY Flexible Multifunctional Bendable Integrated Light-Weight Ultra-Thin Systems Project reference: 287568 Instrument: Integrating Project Contact Coordinator: Prof. Frank ELLINGER Tel: +49 351 463 38734 [email protected] Operational manager: Dr. Corrado CARTA Tel: +49 351 463 42511 [email protected] Fax: +49 351 463 38736 Affiliation and Address: Chair for Circuit Design and Network Theory, Dresden University of Technology, Barkhausenbau 119, Helmholtzstrasse 18, D-01069 Dresden GERMANY Vision & Aim FLEXIBILTIY aims at advancing the competitiveness of Europe in the area of multifunctional, ultra-lightweight, ultra-thin, bendable organic and large area electronics (OLAE). With OLAE, technology systems can be fabricated on a simple piece of foil or even paper resulting in low fabrication costs per area, e.g. 8 to 2 €/m2 for roll-to-roll (R2R) printed technology. A construction kit including the following OLAE components is developed: disposable and rechargeable batteries, solar cells, DC charging electronics, loudspeakers, audio amplifiers, analogue signal generators, motion and temperature sensors, high-frequency receiver circuits for wireless data communication, as well as a touch screen. By specific combinations of these components, a variety of novel multifunctional systems is enabled. Based on a fully printed sound module, several complex demonstrators will be defined and investigated. Considered systems are: • Textile integrated audio module including broadcast radio and solar supply (refer to Fig. 1) Web site: www.FLEXIBILITY-FP7.eu • Active receiver tag for wireless streaming of acoustic data and advertising (refer to Fig. 2.) Timeline: Start Date: 01/09/2011 End Date: 31/08/2015 • Security tag system with acoustic alarm, motion and/or temperature sensors (refer to Fig. 3) Budget: Overall Cost: 6 887 022 EUR Funding: 4,899,000 EUR Project Partners: • Technische Universität Dresden (TUD), DE • Enfucell Oy (ENF), FI • Technische Universität Chemnitz, DE • SIEMENS AG (SIE), DE • Eidgenössische Technische Hochschule Zürich (ETH), CH • EXODUS A.E.

(SMA), IT • Varta Microbattery GMBH (VAR), DE • Konarka Austria Forschungs und Entwicklungs GMBH (KON), AT • Teknologian Tutkimuskeskus (VTT), FI For the realisation of these systems, the advantages of several flexible OLAE technologies are combined, while keeping cost issues in mind: a) R2R printing for components requiring large areas (e.g. loudspeaker, high-power audio amplifiers and solar cells), 3-D integration, as well as integration of heterogeneous devices on one single substrate; and b) Compact (down to 10 μm gate length), fast (> 200 MHz transit frequency, mobilities > 10 cm2/Vs), low-loss IGZO (Indium Gallium Zinc Oxide) thin-film technology to enable wireless communication systems. To make efficient circuit development in standard CAD tools possible, design-kits including scalable models and automated layout templates are developed. Interface and packaging issues are studied for full system integration on a common flexible foil enabling bending radii down to 1 cm. FLEXIBILITY combines the complementary competences of 3 large companies, 4 SMEs, 1 research institute and 3 universities. Involved countries are Austria, Finland, Germany, Italy, Greece and Switzerland. Fig. 1.
