Abstract
The present subject matter discloses devices, systems, and methodologies for harvesting power from environmentally induced vibrations. Piezoelectric devices () and structures are disclosed that may be employed in combination with electro-magnetic () or capacitive () elements to enhance the power harvesting capabilities of the piezoelectric devices (). The electromagnetic () and capacitive () elements may be used to assist in maintaining system mechanical resonance in order to maximize energy harvesting capabilities. 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.
