CityU new droplet-based electricity generator: A drop of water lights up 100 small LED bulbs [CityU NewsCentre]

A research team led by scientists from City University of Hong Kong (CityU) has recently developed a new form of droplet-based electricity generator (DEG).

It features a field-effect transistor (FET)-like structure that allows for high energy-conversion efficiency, and its instantaneous power density is increased by thousands of times compared to its counterparts without FET-like structure.

This groundbreaking achievement can help to advance scientific research into water energy generation and tackle the energy crisis.

The research was led by Prof. WANG Zuankai from CityU's Department of Mechanical Engineering; Prof. ZENG Xiaocheng from the University of Nebraska-Lincoln, US; and Prof. WANG Zhonglin, Founding Director and Chief Scientist at the Beijing Institute of Nanoenergy and Nanosystems of Chinese Academy of Sciences.

Their findings were published in the latest issue of the highly prestigious scientific journal Nature under the title “A droplet-based electricity generator with high instantaneous power density”. (Read more)
