Design of Acoustic Energy Harvesting Unit Using Piezo-Electric Diaphragm

Popis výsledku v původním jazyce

An Acoustic Energy Harvester was designed to convert sound energy produced from speakers at certain frequency to electric energy. The harvester used Piezo-electric buzzer. The design process followed an experimental approach. It included open circuit experiment as well as closed circuit experiments. The open circuit experiment aimed at finding a good initial guess for incident sound frequency for optimum energy harvesting while closed circuit experiment aimed at finding the suitable circuit electrical impedance that would maximise energy harvesting at the frequency obtained from the initial guess. The proposed design can harvest power of 0.043 µW, with voltage of 21 mV and current of 2.05 µA, at a power harvesting density of 2.8x(10)^(-9) W/cm^2. These results are achieved at incident sound of sound pressure level (SPL) of 118 dB and frequency of 466.2 Hz.
