Researchers develop water-tube-based triboelectric nanogenerator for efficient ocean wave energy harvesting

The ocean covers about 70% of the Earth’s surface area and is the largest reservoir of energy. Researchers have been exploring the approach for harnessing ocean energy to solve the world energy crisis and pollution problems caused by thermal power generation. The nanogenerator, including piezoelectric, triboelectric, and pyroelectric nanogenerators, is one of the key technologies for mechanical energy conversion. The triboelectric nanogenerator (TENG) makes use of the triboelectric effect and electrostatic induction to harvest mechanical energy based on contact or sliding electrification.
