Energy Harvesting Aspects of Wireless Sensor Networks: A Review

Abstract

Energy harvesting 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 harvesters provide a very small amount of power for low-energy electronics. The energy sourced from energy harvesters is present as ambient background and is free.
