Research and Analysis of the Droplet-Based Electricity Generator Based on a Rotating Structure

With the development of science and technology, the social demand for energy is also increasing. However, the traditional method of energy supply primarily relies on non-renewable resources for energy conversion. While this conventional approach can expedite the energy conversion process, it also results in irreversible ecological hazards. To solve the above problems, the use of renewable clean energy is proposed. In this paper, a droplet generator is proposed to integrate the rotating structure with the body effect power generation for the tiny energy of raindrops. This droplet generator can increase the speed of droplets leaving the dielectric layer and reduce the effect of continuously falling droplets on the droplet-based electricity generator (DEG). It is demonstrated that the instantaneous power of the generator can reach 0.9 mW, which can be a good solution to the power supply needs of some small power supply equipment, and thereafter is beneficial to the self-powering of the equipment in rainy days.
