Flow inside the Droplet in AC Electrowetting
초록
We found that there exists a flow inside a droplet in AC electrowetting, which is distinct from DC electrowetting. In order to investigate the origin of the flow inside the droplet, we performed an experiment and numerical simulation. It is conjecture, based on the results of the experiment and numerical simulation, the flow is caused by the so called induced-charge electroosmosis at high frequencies, and by droplet oscillation at low frequencies.
