Structure and Mechanical Analysis of Single Cantilever Piezoelectric Energy Harvester

Abstract

Cantilever energy harvester has become the main structure in piezoelectric energy harvester. There are two different methods to build their model. One is lumped parameter model; the other is distributed parameter model. By building their govern equation and solving them, amplitude-frequency characteristics, power and natural frequency of the model are obtained. Comparison of model frequency and amplitude are made between two models. Problems, scope of application and correct method for energy harvester are also given which provides reliable theoretical reference and makes solid foundation for energy harvester design.
