Printed functionality means superimposing different large area roll-to-roll (R2R) manufacturing techniques (for example, different printing techniques, hot embossing, laser processing, evaporation, etching, etc.) to fabricate different functional components and modules for Printed Intelligence applications. These applications can be passive and active electronic, optic and optoelectronic components, different indicators, sensors and diagnostic products. New material solutions and R2R large-area manufacturing processes enable the fabrication of these functionalities on different flexible substrates (plastic, paper, fabrics, metal foils, etc.). The aim is to develop cost efficient R2R manufacturing techniques, material solutions and completely new products, for example lighting and signage elements based on organic light-emitting diodes (OLED), organic solar cells and light detectors, printed batteries and low-cost healthcare diagnostic tools.
VTT transfers laboratory-scale device manufacturing know-how to the pilot level and demonstrates pilot-level manufacturing of the above mentioned components, modules and functionalities. This goal is strongly supported by wide material know-how in organic and inorganic materials and a world-class pilot manufacturing environment.
