  • 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.
