In this paper we investigate the effect of electrode size, channel height, and voltage variations on droplet actuation.
For the numerical analysis, the effects of gaps between electrodes are assumed to be negligible; hence the actuation will be continuous.
It is apparent that by increasing the actuation voltage, which results in a larger change in contact angle, the droplet stretches further (Figures 3, a, b and c).
We investigated the effect of electrode size to predict the optimum configuration in which the velocity is maximum for a given actuation voltage.
Each set of data is used to illustrate one specific actuation voltage.
We presented the results of the numerical simulation of droplet actuation via electrowetting.
