Abstract:
A device for cleaning an object surface, including a substrate provided on the object surface, a plurality of electrodes provided on the substrate, a dielectric layer provided on the substrate to cover the electrodes, and a control device supplying an alternating-current (AC) power to the electrodes including supplying a first AC power having a predetermined first frequency and a predetermined first voltage to the electrodes during a first time period to vibrate a droplet on the surface of the object by a periodic change of an electrostatic force generated at the electrodes, the first frequency being set to the resonant frequency of the liquid droplet.
