摘要：
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.
