A droplet during transition from a grounded electrode to an activated one (top view). Activated electrode is indicated in red. Electrowetting force, few (black arrows) and dewetting force, fdew (white arrows), on the triple point contact line are shown. a Droplet transition on square shape electrodes. b Droplet transition on rectangular electrodes with short width
