Large area sensing surface have strong interest for many applicative sectors: transport, health, building, industrial, user interface… Printed electronics offers breakthrough technical solutions to fulfill these applications. Indeed printed sensors, addressed by printed oTFT matrix and circuits, heterogeneously connected to classical Silicon microprocessor for the signal processing, offers unreached solutions when multipoint, large area and flexibility are required. Recent developments in printed organic "CMOS" circuits, OTFT backplanes and sensors obtained on PICTIC large area Sheet-To-Sheet printing platform will be presented with vision on future potential applications
