The research was led together by Professor Wang Zuankai from CityU's Department of Mechanical Engineering, Professor Zeng Xiao Cheng from University of Nebraska-Lincoln, and Professor Wang Zhong Lin, Founding Director and Chief Scientist from Beijing Institute of Nanoenergy and Nanosystems of Chinese Academy of Sciences. Their findings were published in the newest subject of journal Nature. Hydropower is nothing new. About 70% of the earth's surface is coated by water.

For instance, a standard droplet vitality generator based on the triboelectric impact can generate electricity induced by contact electrification and electrostatic induction when a droplet hits a surface. However, the quantity of fees generated on the surface is proscribed by the interfacial impact, EcoLight and EcoLight products consequently, the vitality conversion effectivity is quite low. So as to enhance the conversion effectivity, the research team has spent two years developing the DEG.
Its instantaneous power density can attain up to 50.1 W/m2, thousands occasions higher than other related devices with out using FET-like design. And the energy conversion efficiency is markedly larger. Professor Wang from CityU identified that there are two crucial elements for the invention. First, the staff discovered that the steady droplets impinging on PTFE, energy-saving LED bulbs an electret materials with a quasi-everlasting electric charge, provides a brand new route for the accumulation and storage of high-density floor EcoLight charges. They discovered that when water droplets continuously hit the floor of PTFE, the floor prices generated will accumulate and progressively reach a saturation. This new discovery helped to beat the bottleneck of low charge density encountered in earlier work. Another key function of their design is a novel set of constructions just like a FET, which is a Nobel Prize in Physics profitable innovation in 1956 and has develop into the basic building block of modern electronic devices nowadays. The system consists of an aluminium electrode, and EcoLight products an indium tin oxide (ITO) electrode with a film of PTFE deposited on it.
The PTFE/ITO electrode is chargeable for the charge technology, storage, and induction. When a falling water droplet hits and spreads on the PTFE/ITO surface, it naturally "bridges" the aluminium electrode and the PTFE/ITO electrode, translating the unique system into a closed-loop electric circuit. With this particular design, a excessive density of floor expenses can be accumulated on the PTFE via steady droplet impinging.
