Patent ID: 8011759

Claim:
A liquid droplet transport apparatus which transports a conductive liquid droplet, the liquid droplet transport apparatus comprising: a substrate; a first electrode and a second electrode which are arranged on a surface of the substrate; an electric potential-applying mechanism which applies electric potentials to the first electrode and the second electrode respectively; a resistor layer which is arranged on the surface of the substrate so that the resistor layer makes contact with both of the first electrode and the second electrode, and the resistor layer, makes electric conduction to both of the first electrode and the second electrode, and which causes an electric potential drop between the first and second electrodes when the electric potentials applied to the first electrode and the second electrode by the electric potential-applying mechanism are different; and an insulating layer which covers the first electrode, the second electrode, and the resistor layer, wherein the liquid repellence of an surface of the insulating layer on which the liquid droplet is placed is lowered as an electric potential difference is increased between the surface of the insulating layer and corresponding one of the first and second electrodes and the resistor layer covered with the insulating layer.
