Abstract :
A numerical model for in-plane electret power generators has been developed. Through detailed comparison, we have confirmed that the response of the present model is in good agreement with our experimental power generation data. Electrostatic force both in the horizontal and vertical directions is examined with the model computation. We also propose an electrode arrangement for reducing the in-plane unidirectional damping force. With this arrangement, the damping force of the electret generator becomes similar with that of the velocity-damped resonant generator.
