摘要

为了给微型传感器持续稳定地供电

利用聚偏二氟乙烯（PVDF）薄膜受外部激励产生大挠度变形来产生更多的电能。通过使不同长度的PVDF薄膜产生不同程度的位移

来探究PVDF薄膜变形与发电量的关系。有限元分析结果表明:在同一长度的PVDF薄膜中

发电量随位移的增大而增大。分别将长度为4.1

7.3

17.1 cm的PVDF薄膜发电情况进行比较

结果表明:三种尺寸都有一个共同的现象

当位移与PVDF薄膜的长度比值接近0.81时

输出功率最高。

Abstract

In order to provide continuous and stable power supply to micro sensors

using large deflection deformation of polyvinylidene（PVDF） thin film under external excitation to generate electric energy

to power micro sensor.The relationship between PVDF thin film deformation and power generation is explored by making PVDF thin films of different lengths produce different degrees of displacement.The finite element analysis results show that in the same length of PVDF thin film

the power generation increases with the increase of displacement.Comparing the power generation of PVDF thin films with lengths of 4.1

7.3

and 17.1 cm

respectively

these three sizes have a common phenomenon: output power is the highest when the ratio of the displacement to the length of the PVDF thin film is close to 0.81.
