Jumping of a Droplet on a Superhydrophobic Surface in AC Electrowetting

AC 전기습윤을 이용한 초발수 표면에서의 액적의 점프

We found that a droplet placed on a superhydrophobic surface jumps upward when we controlled the electrical wetting tension appropriately by applying AC voltage. We investigated how the surface deformation and jumping phenomenon of a droplet are affected by applied frequency under constant voltage. We found that a droplet jumps up continuously at a resonance frequency.
