Electromagnetic Energy Harvesting is a process that captures energy from electromagnetic waves, such as those emitted by radio signals, Wi-Fi, or cellular networks. This technology converts these waves into usable electrical energy, which can power small devices or sensors, especially in remote locations where traditional power sources are unavailable. The harvested energy can be stored in batteries or used immediately to operate devices. This method is beneficial for creating sustainable energy solutions, reducing reliance on batteries, and enabling the development of Internet of Things (IoT) applications that require continuous power without frequent maintenance.
