LIQUID DROPLET TRANSPORTING APPARATUS, AND VALVE, MEMORY, DISPLAY UNIT USING THE LIQUID DROPLET TRANSPORTING APPARATUS

摘要

A liquid droplet transporting apparatus includes a first electrode which is arranged on a surface of a substrate, a second electrode which is arranged apart from the first electrode on the surface of the substrate, an insulating layer which is arranged to cover each of the first electrode and the second electrode, and a liquid repellent property on a surface of the insulating layer changes according to an electric potential difference between the electrode and an electroconductive liquid droplet on the surface, and a third electrode which cooperates with the second electrode to detect the liquid droplet on the second electrode. Consequently, it is possible to transport a liquid droplet between two areas, and also to detect as to in which area out of the two areas, the liquid droplet exists.
