摘要

本文对压电振动能量采集器弹性层的超材料结构尺寸进行了设计。由于通过改变超材料结构的尺寸来控制PVEH的弯曲刚度，因此可以通过优化超材料结构的尺寸来提高器件的性能。通过对具有不同超材料结构尺寸的三种PVEH的有限元分析，发现超材料结构最小的PVEH比具有最大超材料结构的PVEH共振频率降低16%，发电量提高70%。

Size Optimization of Metamaterial Structure for Elastic Layer of a Piezoelectric Vibration Energy Harvester

In this paper, we design the size of metamaterial structure for elastic layer of piezoelectric vibration energy harvester(PVEH). Since controlling bending stiffness of the PVEH by changing the size of metamaterial structure, it is possible to improve device performance by optimizing the size of the metamaterial structure. In the FEM analysis of three types of the PVEH having different size of metamaterial structure, the PVEH which has smallest metamaterial structure reduces the resonance frequency by 16 % and improves the power generation by 70 % compared to the PVEH which has largest metamaterial structure.
