摘要： A device for harvesting an external source of energy includes an electricity generating device, a flexure, and a first stop. Displacement of the flexure is limited by the first stop. The flexure has a vibration amplitude, wherein the vibration amplitude is amplitude the flexure would have if unconstrained by the first stop. The first stop allows the flexure to oscillate with a vibration amplitude that is higher than displacement of the flexure as limited by the first stop. The electricity generating device generates electrical energy while the first stop allows the flexure to oscillate with the higher vibration amplitude.

摘要： A device for harvesting an external source of energy includes an electricity generating device, a flexure, and a restoring spring. The electricity generating device generates electricity based on movement of the flexure. The flexure has a first stable position. When disregarding presence of the restoring spring the flexure also has a second stable position different from the first stable position. The restoring spring is positioned so when the flexure snaps from the first stable position toward the second stable position the restoring spring provides a restoring spring force to restore the flexure toward the first stable position. Substantially greater force is needed to snap the flexure from the first stable position toward the second stable position to overcome the restoring spring force than is required to snap the flexure from the second stable position toward the first stable position.

摘要： An energy harvesting system includes a composite structure that includes a base spring and a first piezoelectric element. The first piezoelectric element is mounted on the base spring. The base spring has a base spring thickness, a base spring length, and a base spring width. The base spring is for vibrating around an axis parallel to the base spring width. The base spring thickness varies from position to position along a direction parallel to the base spring length. The base spring thickness varies to provide the first piezoelectric element with constant strain when the base spring vibrates around the axis parallel to the base spring width.
