摘要：

The same mechanism responsible for contact angle saturation of electrically stressed aqueous droplets also clamps the electromechanical force exerted on aqueous liquids in structures using dielectric-coated electrodes. Alternating current frequency strongly influences the upper limit imposed on this force. Furthermore, studies of transient, field-induced motion suggest that this mechanism is suppressed when the contact line moves rapidly along the coated electrodes.
