PIEZOELECTRIC ENERGY HARVESTER DEVICE WITH A STOPPER STRUCTURE, SYSTEM, AND METHODS OF USE AND MAKING |
摘要 |
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 stopper connected to the mass and/or the second end of the resonator beam, where the stopper is configured to prevent contact between the second end of the resonator beam and the package. Also disclosed is a system, a method of powering an electrically powered apparatus, and methods of producing an anergy harvester device. |
