This paper presents numerically obtained results for the net force on a fluid slug transported by dielectrophoresis (DEP) and compares it with previously obtained data for the electrowetting on dielectric (EWOD) effect. The net DEP force is shown to be strongly peaked when a droplet interface is located near the edge of a charged capacitor, and reduces to the well-known lumped parameter result in the appropriate limits. The effect of electrode spacing is seen to have an inversely proportional effect upon the force experienced by the droplet, and the effect of increasing droplet curvature is observed to increase the net force on the droplet.
