Abstract
The understanding of electrowetting phenomenon is an essential way for controlling tiny droplets on dielectric material surfaces. In conventional viewpoint, the shape of droplet is determined by the contact angle which is influenced by applied electric field. In this paper, we present a new approach to modeling and analyzing the electrowetting phenomenon. It is based on electromagnetic body force and surface tension as well as the initial contact angle. The pressures on the surface of droplet are calculated by using the revised Kelvin's formula, the hydrostatic equation and the surface tension due to surface curvature. The electrowetting phenomenon was successfully modeled and analyzed using the proposed approach.
