Zusammenfassung:A device for harvesting an external source of energy includes an electricity generating device and a flexure. The piezoelectric flexure has a first stable bowl-shaped position and a second stable bowl-shaped position. The electricity generating device generates electricity based on movement of the flexure. The flexure remains in the first stable bowl-shaped position until a force provided by the external source of energy causes the flexure to move from the first stable bowl-shaped position toward the second stable bowl-shaped position.
