Abstract

We investigate piezoelectric energy harvesting on a locally resonant metamaterial beam for concurrent power generation and bandgap formation. The mechanical resonators have piezoelectric elements which are connected to electrical loads to quantify their electrical output in the locally resonant bandgap neighborhood. Electromechanical model simulations are followed by detailed experiments on a beam setup with 9 resonators. The locally resonant bandgap is measured and a resistor sweep is performed for each resonator to capture the optimal power conditions. Experimental efforts also include the DC combination of the separate harvester power outputs through full wave rectification of each output voltage.
