Compared with traditional electrowetting-on-dielectric (EWOD), orbital EWOD is a newly observed droplet manipulation phenomenon on superhydrophobic surface, which has the advantages of high speed, antigravity, and no pollution broad application prospects. However, current research electrowetting structured electrodes focuses statistical characteristics collection, movement process single droplets still unclear. The study eccentric correction helps us to better understand influence local energy provide ideas for designing hybrid circuits that can realize more functions. Based existing EW driving force models experiments surfaces, factor introduced, phase-field simulation software COMSOL Multiphysics used simulate motion 10 μL in 250 V (1000 Hz) straight orbit, inclined circular arc eccentricity coplanar electrodes. traveling modes are summarized. In spreading radius about 1.09 times initial radius, maximum inclination angle 9.8°, 24.7 μN at an offset 297 μm.
