Energy harvesting is a promising technique to gather small amounts of ambient energy for use in devices where traditional power sources like batteries are not feasible. This method is widely used in various applications, including body sensor networks, and unreachable remote systems. This article explores the importance and potential of materials in energy harvesting systems and provides insight into the idea of energy harvesting.
What is Energy Harvesting?
Energy harvesting, also known as power harvesting, energy scavenging, or ambient power, is a process of obtaining energy from different external sources such as solar power, thermal energy, wind energy, salinity gradients, and kinetic energy (ambient energy) and storing it for use in small, wireless, and autonomous devices. This technique eliminates the need for regular battery replacements and allows electronic devices to operate in locations without a traditional power source.
