PZT 시스템과 전기 시스템의 최적 설계를 통한 Energy Harvesting 효율 향상
Energy Harvesting Efficiency Enhancement by Optimal Design of PZT and Electric System
초록
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.
