Abstract

This paper studies the dynamic electromechanical response of S-shaped piezoelectric energy harvesters both numerically and experimentally. The resonant frequency and output voltage of the harvesters excited by bending/torsion vibration were analyzed by three dimensional finite element method. The resonant frequency and output voltage were also measured, and a comparison was made between analysis and experiment. The effects of waviness ratio, proof mass and load resistance on the dynamic electromechanical fields and output power were then discussed in detail.
