Abstract: With the increasing energy demands and environmental issues day by day, there is a need for sustainable alternatives. Noise pollution has always been a topic to worry about. So, we are utilizing noise or sound by converting it into electrical energy using piezoelectric sensor. The piezoelectric sensors use the piezoelectric effect to transform mechanical energy, for instance, sound waves into electrical energy. The potential applications of this technology are numerous, including energy harvesting from traffic noise, music, and even heartbeats. To the study in the field of piezoelectric energy collecting sensors Polyvinylidene fluoride (PVDF) and lead zirconate titanate (PZT) is used. The maximum power outputs achieved in these studies vary between 0.77 mW to 51.6 mW, depending on what is the outline of the energy harvester and the type of sound source used. Use of piezoelectric sensors for energy harvesting has great potential for generating renewable energy from ambient sound sources.
