Abstract
Screen-printed piezoelectric flexible microgenerators are presented. The features of this work are the deposition of multilayers of P(VDF-TrFE) thin films and organic electrode of PEDOT:PSS. Dielectric, ferroelectric and direct piezoelectric constants are reported as a function of film thickness. Direct voltage coefficient g31, measured for the first time, is shown to reach 0.118 V.m/N. In open-circuit conditions, the microgenerators submitted to four-point bending experiments can produce strain-induced voltage of 10 V with an energy density of 275 μJ/chi3.
