A Novel Bird-Shape Broadband Piezoelectric Energy Harvester for Low Frequency Vibrations

This work presents a novel bird-shaped broadband piezoelectric energy harvester based on a two-DOF crossed beam for low-frequency environmental vibrations. The harvester features a cantilever mounted on a double-hinged beam, whose rotating motions effectively diminish its natural frequencies. Numeri...
