Abstract

The micro power generators that depend on converting the ambient energy into usable electrical energy for portable electronic devices have attracted much attention in recent years. A novel microfluidic power generator which is based on reverse electrowetting in a microchannel geometry was presented by Tom Krupenkin and J. Ashley Taylor. This generator overcomes the defects such as low output and low resource utilization of traditional energy converters. Understanding the parameters influencing output of this generator is a key to enhance the power output of it. This paper discussed the effects of factors on generator output by numerical simulation. The results show that promising performance of REWOD-based power generator can be achieved by choosing a thinner dielectric film with high dielectric constant and high break strength, and increasing the droplet oscillation frequency.
