Mathematical model is established to evaluate the dynamic response of the micropump. Electro-mechanical coupling effect is considered in evaluating the electrostatic force applied on the pump electrode. Boundary Element Method is employed to solve the three dimensional Laplace equation that the potential difference satisfies. A combination of Assumed-mode method and Boundary Element Method is employed to solve the governing equation of the pump diaphragm. Newmark iteration method is utilized to solve the decoupled ordinary differential equations. Deflection of the oscillated diaphragm is demonstrated to evaluate the performance of the electrostatic pump. Amplitude and frequency of the potential difference between the two electrodes are investigated. |  | View paper | | ISBN: | 0-9666135-7-0 |
