New droplet-based electricity generator: A drop of water generates 140V power, lighting up 100 LED bulbs

Science Daily  February 5, 2020 An international team of researchers (USA – University of Nebraska, Hong Kong, China) found that the continuous droplets impinging on Polytetrafluoroethylene (PTFE) provides a new route for the accumulation and storage of high-density surface charges. The device consists of an aluminium electrode, and an indium tin oxide (ITO) electrode with a film of PTFE deposited on it. The PTFE/ITO electrode is responsible for the charge generation, 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 original system […]
