    Abstract

    Fully mass printed, flexible and truly polymeric organic field effect transistors consisting of a three layer dielectric made of CYTOP (low-k), PVA (intermediate) and P(VDF-TrFE-CTFE)(high-k) are introduced. Gravure-, flexo-and screen printing were selected as highly productive manufacturing technologies. These OFETs work at strongly reduced voltages and show high field effect mobility (µ?=?0.2??cm2/Vs) and remarkable good bias stress stability at very high current density (50??µA/mm). Fully printed OFETs are used for the realization of ring oscillators working in the kHz regime at reduced supply voltage (10??V). In combination with printed fully polymeric piezoelectric loudspeakers, this work shows for the first time fully printed flexible audio systems.
