Abstract

Abstract: In this project, a relativelyless explored source of green energy that is sound energy is proposed. Randomsound energy around us can be treated as a source of electric power after theirefficient conversion using suitable transducer. An efficient method ofproducing usable electric power from available random sound energy is presentedhere. Piezoelectric transducers are used for conversion of sounds into electricenergy. Piezoelectric is used to describe the materials that accumulate acharge as a result of piezoelectric effect. The resultant electric power wasused to charge a mobile. By converting sound into electrical energy with thehelp of piezoelectric sensor a mobile can be fully charged. In the currentcondition only 11% of renewable resources are being used. Due to this projectuse of renewable sources would increase and the problem of charging a mobile inour day to day life will decrease.
