Energy harvesting refers to the extraction of energy from the environment. Available energy is captured and used for other purposes.
A concrete example from the smart home sector: The essentials Radiator Thermostat Energy Self-Sufficient BT It is not powered by batteries, but draws the energy it needs to function from the available heating system via an integrated thermoelectric nanogenerator. The radiator thermostat therefore does not rely on any other energy sources. This principle of energy self-sufficiency is called energy self-sufficiency.
