Design of Piezoceramic Length for Cantilever-Type Piezoelectric Generators

Abstract

The power harvesting from ambient vibrations can be stored to support wireless sensors which are applied for temperature and humidity measurement and machinery acceleration monitoring. Such vibration-based generators can automatically transform mechanical energy into electrical energy to supply the maintenance-free, wireless electronics. The piezoelectric effect is an effective method of electromechanical transduction. Cantilevertype piezoelectric generators with piezoelectric patches have recently received increasing attention over the past decades [1].
