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.
