Paper Title:
Performance Research of a Novel Spiral Piezoelectric Harvester
  Abstract

Piezoelectric materials generate electricity when they are subjected to mechanical strain. This paper presents an innovative design platform of piezoelectric energy harvester with variable curvatures and sections. Firstly, the effects of the proof mass position on the spiral laminated beam with PZT-5H bonded on the surface are analyzed. Secondly, the dynamical performances of the piezoelectric harvester with different shape are investigated. The results, which are gotten through ANSYS software, show that the first three order natural frequencies increase linearly while the distance from the free end increases. The voltage distribution variates acutely because of the coupling of the bending and twisting actions in the beam. The simulation data will provide a theory analysis foundation for the engineering, design and application of harvester.
