Energy harvesting from piezoelectric is proved to be a viable technology to source low power electronic devices. In this paper, piezoelectric energy harvester is designed such that the energy is harvested by utilizing the switching of the MOSFET in DC-DC converter, which becomes an integral part of modern industrial equipment. Energy harvesting is realized by piezoelectric and converse effect of piezoelectric material. The harvester is designed to have transmitter and receiver piezoelectric separated by metal plate, connected across the drain and source terminals of the MOSFET. The performance of the harvester is experimentally evaluated with boost converter for supercapacitor storage.

事实证明，从压电体收集能量是一种可行的技术，可为低功率电子设备提供电源。本文设计了压电能量收集器，以便利用DC-DC转换器中MOSFET的开关来收集能量，这成为现代工业设备的组成部分。能量收集是通过压电和压电材料的反作用来实现的。收割机的设计是使发射器和接收器的压电体被金属板隔开，并跨接在MOSFET的漏极和源极之间。使用升压转换器对超级电容器存储进行实验评估了收割机的性能。
