Energy harvesting is the process of capturing and converting small amounts of ambient energy, such as light, heat, vibration, or motion, into usable electrical power. This technology is key to developing self-powered electronic devices and systems that can operate autonomously without the need for external power sources. Energy harvesting has applications in a wide range of fields, including wearable technology, IoT devices, wireless sensor networks, and remote monitoring systems. Researchers in this area are focused on developing efficient and cost-effective energy harvesting solutions that can maximize energy capture and conversion for various applications.
