Outline of Final Research Achievements

We have demonstrated that fully-printed organic thin-film transistors with excellent electrical performances. The integrated circuits (RS-Flip flop) were operated successfully at low operation voltage and with high operation speed. Furthermore we demonstrated fully printed organic circuits fabricated on one-micron-thick films with extremely light (2 g/m2) and excellent mechanical stability. These results represent significant progress in the fabrication of fully printed organic TFT devices and circuits for use in unobtrusive electronic applications such as wearable sensors.
