  • Piezoelectric energy harvesting bending structure and the method of manufacturing thereof
    Patent number: 11387403
    Abstract: A piezoelectric bimorph cantilever beam system includes a shim having a first main surface, a second main surface opposite the first main surface, a proximal end connected to an anchor, and a distal end opposite the proximal end. The system further includes a first piezoelectric layer laminated on the first main surface of the shim and a second piezoelectric layer laminated on the second main surface of the shim. A first beam stiffener is provided over the first main surface of the shim adjacent to the anchor with the first beam stiffener at least partially covering the first piezoelectric layer. A second beam stiffener is provided over the second main surface of the shim adjacent to the anchor with the second beam stiffener at least partially covering the second piezoelectric layer.
    Type: Grant
    Filed: July 5, 2018
    Date of Patent: July 12, 2022
    Assignees: VERMON S.A., UNIVERSITE GRENOBLE ALPES
    Inventors: Libor Rufer, Skandar Basrour, Emilie Trioux, Guillaume Férin, Claire Bantignies, Hung Le Khanh, Bogdan Rosinski, An Nguyen-Dinh

  • Piezoelectric energy harvester system with composite shim
    Patent number: 10097112
    Abstract: A vibrational multi-morph piezoelectric energy harvester includes a composite shim having a parallelepiped form with a thickness dimension made smaller than width and length dimensions, and having a stiffness shifting from one extremity to the other extremity to minimize mechanical constraints developed at a clamping area; a seismic mass mounted at an end opposite to the clamping area to mechanically match the system to the surrounding vibration resonance; one or more piezoelectric layers laminated on said composite shim; and electrodes plated onto the one or more piezoelectric layers for connection to an electronic harvesting circuit, a battery, or a super capacitor.
