Development of a multi-layer cylindrical rotating electret generator with increased power densit

Electrostatic electret generator has attracted a lot of attention in recent years, but their low power density cannot be ignored. Based on the existing research, this paper increases its from two aspects, including in-plane and in-space aspects. In plane aspect, through simulation analysis, we can draw conclusion that output increased effectively by using bipolar charging method. From perspective space, several times connecting ends multi-layer generation structure. By integrating method into electrostatic generator, increased, which is suitable to application higher energy requirements specific field certain prospect.
