Since 2007, Cetemmsa has been an active member of the Organic Electronic Association (OE-A), by participating in roadmaps definition and by being the speaker of the Smart Textile group within the association.
In 2009-10, Cetemmsa decided to go further, and lead a demonstrator project with 3 other OE-A members: UAB-Cephis, HC Starck and Varta Microbatteries.
This demonstrator joins together smart textiles and printed electronic to build an eye catching electroluminescent flag which moves in the wind.
It is built from an electroluminescent multilayer device printed on a commercial textile by Cetemmsa (Centre de Tecnologia Empresarial de Mataró i Maresme), and connected to a hybrid inverter composed of inkjet printed passive components and of SMD inverter chips hybridised on a circuit printed on polyimide. A fully printed RC circuit switches off the EL textile approx. 10s after the user has switched on the demonstrator.
The OE-A Flag demonstrates that EL textile can provide light for signage / marketing purposes while still keeping the fundamental property of textiles, which is its flexibility. EL is also a robust technology, virtually indifferent to environmental conditions, and thus not requiring a tough, only foldable and not yet good enough encapsulation material.
In this project, Varta Microbatteries provided the Li-ion batteries, UAB-Cephis designed and printed the inverter circuit, and carried out components connections, HC Starck provided high conductivity PEDOT:PSS for its use as transparent conductive electrode of the EL assembly; and Cetemmsa printed the EL textile and passive components, and carried out the inverter encapsulation and the prototype design and assembly.
The demonstrator was officially presented at LOPE-C 2010 last June 1st. in presence of different members of the European commission.
Cetemmsa is a technology centre with over 18 years experience in carrying out applied research on Smart Materials and Smart Devices.
The results of this research are the basis of joint projects with companies for innovation and experimental development of smart products - Smart Innovation - that bring new uses and experiences to a wide range of economic sectors.
