Abstract

The present work investigates the effect of variation of length of electrode for a EWOD (electrowetting on dielectric) based microfluidic flow. The discussed model takes into account the effect of energy gradient on droplet movement. The voltage and pitch length are kept constant at 60 V and 200μm respectively. The parameter measured is the velocity of the droplet in the direction along channel length. Various configurations were simulated and the best configuration was attributed to the one with the highest and stable energy gradient. Simulations of droplet movement are done on Coventor Ware. The increase in length of electrode has been found to increase the velocity of droplet movement.
