Abstract

Inspired by electromagnetic hydropower station that contains reverse polarized magnet, this paper reports a novel micro electrostatic rotary energy harvester (e-REH) that integrates both positive and negative charged electrets into single rotational energy conversion system. It is the first time successfully demonstrating the feasibility and viability of micro-patterning bipolar charge into single electret sheet for boosting rotary energy harvesting effectiveness. Selectively localized corona charging method with rotational shadow mask is invented to pattern the predefined area with microscale opposite types of charges. With the fabricated prototype, the experimental results show the superior performance of the proposed bipolar e-REH: the output voltage increases over 200% compared to the positive alone and negative alone configurations.
