Abstract
Provided is an electronic image device, which includes a barrel-shaped container, a conductive liquid, an insulating liquid, an electronic image element, a light-transmissive window, a first electrode, a second electrode, and a voltage source. The conductive liquid and the insulating liquid have the same density and different optical refractive indices, are immiscible with each other, and are filled into the barrel-shaped container. The electronic image element is disposed at a first end of the barrel-shaped container and in contact with the conductive liquid. The light-transmissive window is disposed at a second end of the barrel-shaped container and in contact with the insulating liquid. The first electrode is in contact with the conductive liquid and the second electrode forms a capacitive coupling with the conductive liquid. A variable voltage is applied between the first electrode and the second electrode.
