Energy harvesting integration

Definition

Energy harvesting integration refers to the process of capturing and converting ambient energy from the environment into usable electrical energy, which can then be stored in batteries or used to power devices. This approach enhances the efficiency of power systems by reducing reliance on conventional energy sources, such as batteries, and promotes sustainability through the utilization of renewable energy sources. By integrating energy harvesting techniques with battery technologies, devices can achieve longer operational lifespans and minimize the need for frequent battery replacements.
