Analysis of augmented droplet transport during electrowetting over triangular coplanar electrode array

Abstract The improvements in the dynamic performance of droplet movement over a newly designed and fabricated triangular coplanar electrode system utilizing the principle of electrowetting on dielectric (EWOD) is extensively probed and compared with results available in the literature. The process is further explored by developing a model, taking into account the pertinent driving and retarding forces, the role of the effective contact line length and an in-situ evaluation of the contact line friction coefficient. Furthermore, the efficiency of the fabricated digital microfluidic platform is quantified and compared in terms of driving force and velocities.
