Description
Summary:In this paper, we present the results of a preliminary study on the piezoelectric energy harvesting performance of a Zr‐doped PbMg1/3Nb2/3O3‐PbTiO3 (PMN‐PZT) single crystal beam. A novel piezoelectric beam cantilever structure is used to demonstrate the feasibility of generating AC voltage during a state of vibration. The energy‐harvesting capability of a PMN‐PZT beam is calculated and tested. The frequency response of the cantilever device shows that the first mode resonance frequency of the excitation model exists in the neighborhood of several hundreds of hertz, which is similar to the calculated value. These tests show that several significantly open AC voltages and sub‐mW power are achieved. To test the possibility of a small scale power source for a ubiquitous sensor network service, energy conversion and the testing of storage experiment are also carried out.
