Abstract
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.
