Piezoelectric energy harvester device with curved sidewalls, system, and methods of use and making

摘要

The present invention relates to an energy harvester device, which includes an elongate, planar resonator beam comprising a piezoelectric material and side walls extending between first and second ends; a base connected to the resonator beam at the first end with the second end being freely extending from the base as a cantilever; and a mass attached to the second end of the resonator beam. The side walls are continuously curved within the plane of the resonator beam. Also disclosed are a system containing the device, and methods of using and making the device.
