More Information
Summary:The present invention relates to an energy harvester device comprising an elongate resonator beam comprising a piezoelectric material, the resonator beam 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; a mass attached to the second end of the resonator beam; a package surrounding at least a portion of the second end of the resonator beam; and a compliant stopper connected to the package, where the stopper is configured to stabilize motion of the cantilever to prevent breakage. Also disclosed is a system, a method of powering an electrically powered apparatus, and methods of producing an anergy harvester device.
