摘要

研究了压电纤维复合材料悬臂梁俘能器的电学特性

使用有限元法分析了叉指型电极结构尺寸、压电纤维和基板材料厚度对输出电压的影响

并将同等尺寸的d33和d31模式压电纤维材料悬臂梁俘能器发电能力进行对比分析。结果表明:叉指电极结构尺寸对工作于d33模式的压电纤维材料悬臂梁俘能器输出电压影响较大。d33模式俘能器具有能产生高电压、低电流值的特点

当压电纤维和基板材料的最佳厚度比为0.75时

俘能器产生电荷量最大。而d31模式俘能器具有能产生低电压、高电流值的特点

当压电纤维和基板材料的最佳厚度比为0.6时

俘能器的输出电压最大。相对于d33模式压电纤维材料

工作于d31模式压电纤维材料更适合作为发电材料使用。

Abstract

The electrical characteristics simulation of piezoelectric fiber composites cantilever energy harvester is studied.The effect of interdigital electrode dimension and the thickness ratio of piezoelectric fibers to the metal plate on output voltage is analyzed by Finite Element Analysis（FEA）Method.The electricity generating power of the same dimension piezoelectric fiber cantilever energy harvester（d33 and d31 mode）is analyzed.The result shows that the output voltage of the d33 mode is affected greatly when the interdigital electrode dimension is changed.The d33 mode energy harvester generated higher output voltage but lower output current than the d31 mode energy harvester.When the thickness ratio of d33 mode is 0.75

the harvester generates the largest quantity of charge.When the thickness ratio of d31 mode is 0.6

the output voltage of the harvester is the highest.The d31 mode piezoelectric fiber material is more suitable for using as power generation material.
