摘要： A self-cleaning device and a method of operating the same for removing droplet, high viscosity liquid material or mixed material using heating, multi-voltage applying or vibration are disclosed. The self-cleaning device comprises a metal material layer disposed on a solid material layer and a hydrophobic layer disposed on the metal material layer. The metal material layer includes a view member formed of conductive material and a heating member disposed outside or inside the view member, heat is generated from the view member and the heating member when a power is applied to the view member and the heating member, the heat generated from the heating member is delivered to the view member, and droplet existed on a surface of the self-cleaning device is removed or a volume or surface tension of the droplet reduces by the heat generated from the view member and the heat delivered from the heating member.

摘要： 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.

摘要： Self-cleaning device and method using electrical oscillation and mechanical oscillation are disclosed. The 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. Here, electrical oscillation for oscillating a droplet in a horizontal direction is generated by applying a first electric signal to the first electrode, thereby merging the droplets formed on the hydrophobic layer, and 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.
