Abstract: In the realm of energy harvesting, the conversion of sound into electricity is a novel strategy that seeks to capture and harness ambient acoustic energy. With an emphasis on piezoelectric materials, electromagnetic induction, and triboelectric nanogenerators, this paper thoroughly investigates the current approaches and technology for turning sound into electrical energy. Each strategy is assessed based on its effectiveness, suitability, and possible uses. Despite their high sensitivity and ability to transform impact into electric charge, piezoelectric materials have drawbacks such as frequency dependence and brittleness. Although it is simple and reliable, electromagnetic induction usually has a lower efficiency. Although they are very efficient and flexible, triboelectric nanogenerators are sensitive to their surroundings and are prone to wear.
Because of the advancement of technology, humans are now entirely reliant on electrically powered equipment. Blackouts, shortages of electricity, and coal runoff are the results of this. Therefore, the most sought-after alternative energy source for producing power is renewable energy. Wind energy is the second most plentiful renewable energy source, after solar energy. However, we have examined the conversion of sound to electricity in this work. A lot of research is being done in the field of sound to electric conversion.
