This study compares the measured and predicted characteristics of an energy harvester utilizing single crystal lead magnesium niobate-lead titanate (PMN-PT) material. The energy harvester is composed of a cantilever beam with a single crystal PMN-PT patch, a tip mass, a rectifier and an electric load. Characteristics of the energy harvester were studied via both analysis and experiment. A theoretical model was established and experimentally validated. Natural frequency of energy harvester was fixed with tip mass. The generated power was also experimentally obtained for different levels of acceleration. The energy harvester was also used to drive an accelerometer using only energy harvested from ambient vibration.
