Utilization of Piezoelectric Material for Energy Harvesting

Energy harvesting or the process of acquiring energy from surrounding environment has been a continuous endeavour throughout the history. Energy harvesting (also known as power harvesting or energy scavenging) is the process by which energy is derived from external sources (e.g. solar power, thermal energy, wind energy, salinity gradients, and kinetic energy), captured, and stored for small, wireless autonomous devices, like those used in wearable electronics and wireless sensor networks. Energy harvesting is such a broad topic, so we're going to specifically deal with piezoelectric energy harvesting.
