Triboelectric nanogenerators for wind energy harvesting

5G and the Internet of Things have dramatically changed our lives. Sustainably powering distributed electronics and sensor networks is a pressing requirement and a challenge. Traditional fossil fuels not only pollute the environment, but also are not renewable. Especially in today's serious energy and environmental problems, actively promoting the rapid development of micro-energy harvesters can provide an important means for the rational use of resources. Therefore, a new way of supplying electricity is urgently needed in the contemporary world. Harvesting energy from the external environment to drive electronic devices has become a viable approach. Triboelectric nanogenerators (TENGs) convert various mechanical motions into electrical signals by harvesting various forms of mechanical energy in the environment and convert alternating current (AC) signals into stable direct current (DC) signals through power management circuits and power electronic component signals. It can not only solve the problem of converting the collected wind energy into electric energy, but also supply power for subsequent sensors, realizing part of self-driven sensing without external power supply, and without complex control circuits and programs. It has good application prospects in the field of meteorological monitoring.
