Study of Piezoelectric Energy Harvester
This work presents a miniature piezoelectric model that analyses the generated electrical energy occurring from the variations in the acceleration. It consists of a seismic energy harvester or a bimorph whichisfixedtoavibratingsourceatoneendandaproof masstoanotherend.Thebimorphisatgroundpotential and two electrodes are placed at the outer surface of the cantilever beam. A fixed electric load calculates the frequency of vibration and the acceleration thus caused by the virtue of DC output voltage is found to be linear. Various Piezoelectric materials are used to analyze the vibration and acceleration on the model. This energy harvesters find applications in volcanic seismic equipment’s as this modeled system can provide a small amount of energy to detect the seismicwaves.
