Ambient Energy Harvesting

Ambient energy harvesting technologies capture and convert energy from environmental sources like radio frequency signals, indoor lighting, thermal gradients, and mechanical vibrations into electrical power. These systems enable battery-free or self-sustaining operation for IoT devices, wearables, and sensors by eliminating the need for battery replacement or charging.

RF energy harvesting captures power from Wi-Fi, cellular, and broadcast signals. Indoor light harvesting uses photovoltaic cells optimized for low-light conditions. Thermal energy harvesting converts temperature differences into electricity. Vibration harvesting captures energy from movement. Advanced systems combine multiple sources and use power management ICs to efficiently store and distribute harvested energy, enabling devices to operate indefinitely in environments with sufficient ambient energy.
