摘要

介绍了一种丝网印刷柔性压电微发电机。本工作的特点是沉积了多层P(VDF-TrFE)薄膜和PEDOT:PSS有机电极。介质常数、铁电常数和直接压电常数是薄膜厚度的函数。首次测得的直接电压系数g31可达0.118 V.m/N。在开路条件下，经过四点弯曲实验的微发电机可产生10 V的应变感应电压，能量密度为275 μJ/chi3。

Fabrication and characterization of piezoelectric microgenerators for flexible energy harvesting using P(VDF-TrFE) screen-formulated inks

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.
