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

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.
