A Novel Tri-Direction Energy Harvester Using Bimorph Cantilever Structure

Abstract:

Energy harvesting for powering low-power devices has drawn considerable attention over the last decade. This paper reports a novel tri-direction energy harvester to scavenge energy from wind and vibration, or a combination of them. The proposed harvester consists of a triple-level bimorph cantilever with a mass block to harness energy from ambient vibration. The mass block also acts as an aerofoil and bluff body to scavenge energy from wind. Theoretical analysis shows that the maximum output power of the harvester is 2.77 W, and the resonance frequency is 79 Hz.
