Abstract
This paper presents droplet generation experiments using EWOD (Electro wetting on dielectric).EWOD is a technology for manipulating droplets discretely by controlling the surface wettability electrically. Changing the shape of the electrode and the thickness of the spacer, We investigated optimal conditions for the reservoir. When quadrilateral shape is larger than circular shape it is easy to make constriction by deforming the droplet considerably. When the spacer is not the optimum thickness, it cannot be generated. Spacers with a thickness of 0.22 mm are suitable for producing droplets, and bubbles are generated when high voltage is applied. It is desirable to increase the
durability of the device.
