Abstract
A self-cleaning device comprises at least one first electrode disposed on a solid material layer, a first dielectric layer disposed on the first electrode, a hydrophobic layer disposed on the first dielectric layer, and at least one mechanical oscillation unit. Electrical oscillation for oscillating a droplet in a horizontal direction is generated by applying a first electric signal to the first electrode, thereby merging droplets formed on the hydrophobic layer, the mechanical oscillation unit moves the merged droplets in a specific direction or atomizes the merged droplets to remove the merged droplets by generating mechanical oscillation for oscillating the droplet in a vertical direction, and each of the droplets has a volume smaller than 3 μl, and new droplet having a volume more than 3 μl is generated by the merging.
