<br>The research was led together by Professor Wang Zuankai from CityU's Department of Mechanical Engineering, Professor Zeng Xiao Cheng from College of Nebraska-Lincoln, and Professor Wang Zhong Lin, Founding Director and Chief Scientist from Beijing Institute of Nanoenergy and Nanosystems of Chinese language Academy of Sciences. Their findings had been revealed in the newest problem of journal Nature. Hydropower is nothing new. About 70% of the earth's floor is coated by water. Yet low-frequency kinetic power contained in waves, tides, and even raindrops are usually not effectively transformed into electrical vitality due to limitations in present expertise. For instance, a standard droplet power generator primarily based on the triboelectric effect can generate electricity induced by contact electrification and electrostatic induction when a droplet hits a surface.
