Energy Harvesting Using Piezoelectric Materials

Abstract

The need for new energy sources has been growing as a result of the rise in energy consumption and the depletion of non-renewable energy sources. One such method is the use of piezoelectric sensors, which can provide valuable electrical energy by converting mechanical stress into electric potential when pressure is applied to the sensors. The main challenges in designing the system are selection of the materials to be used, environmental that it is being used the type of pressure being applied are all the factors that play vital role in the result. Thus, all these factors should be taken into consideration while developing the system. A sophisticated simulator was used to create the system's proportions and shape. The system's chosen model is unimorph; to create potential, a force is applied to the surface. For the harvester to provide output electric potential, the pressure applied needs to be dynamic (i.e., continually changing). The rectified voltage can be used to power electronics, recharge batteries, or store energy in capacitors.
