Large-area Electronics Based on Organic Transistors

Abstract

We report technical details of large-area sensors and actuators using organic field-effect transistors (FETs). In particular, we focus on stretchable electronic artificial skins (e-skins) for robots in the next generations and sheet-type Braille display with soft actuator arrays. We also present recent progress of reliability and stability issues; encapsulation techniques to suppress chemical degradation and annealing techniques to reduce the effect of DC bias stress. Furthermore, we report inkjet and screen printing process to manufacture 30X30 cm2 organic FET active matrices for applications to large-are sensors.
