Energy harvesting is the process of capturing and storing small amounts of energy from various sources in the environment. This can include energy from sunlight, heat, vibrations, or even movement. The goal is to convert these energy sources into usable electrical power, often for small devices like sensors or wearables. Common methods of energy harvesting include solar panels, thermoelectric generators, and piezoelectric materials. These technologies allow devices to operate without relying on traditional batteries, making them more sustainable and reducing waste. Energy harvesting is increasingly important in the development of Internet of Things (IoT) applications and smart technologies.
