Abstract

The purpose of this study is intended to improve the efficiency of energy harvesting through the optimal design of the PZT system and the electrical system. To improve the efficiency of energy harvesting, it is necessary to increase the output voltage generated from the PZT. In this study, first the mounting position and shape of the PZT which is attached to the cantilever were optimized. Second electric circuit was optimized by using a series connection of a circuit and the electrical resonance frequency. As a result, we improve the output voltage about 5V.
