Harvesting Energy: Principles and Applications

Harvesting energy involves capturing and converting natural or ambient sources of power—such as solar, wind, vibrational, or thermal energy—into usable electrical energy. This process leverages everyday environmental phenomena, enabling wireless sensors, wearable devices, or remote systems to operate independently without batteries. Applications range from solar panels on rooftops to tiny devices that generate power from body heat or motion. The goal is to sustainably gather energy from the environment efficiently, reducing reliance on traditional power sources and supporting the development of self-sufficient, eco-friendly technologies.
