摘要
The present subject matter discloses apparatus and methodologies for fabricating apparatus for harvesting power from environmentally induced vibrations. Piezoelectric devices and structures (1600) are disclosed that employ constant force spring or flexure arrangements (1512) in balanced opposition configurations (1510, 1534) to enhance the power harvesting capabilities of the piezoelectric devices (1600). Power harvesting devices and systems in accordance with the subject technology may concurrently operate as sensors in motion sensitive applications thus providing self-powered monitoring capabilities.
