抄録: In bio-micro devices, numerous functions of liquid flow such as elongation, expansion and transportation are required. Electro-wetting is one of the methods to control the liquid flow. In the present study, a water droplet was elongated in a channel based upon electro-wetting, and the effect of electrode diameter and shape of electrode immersed in a water droplet on the elongation was examined. The elongation increased as a diameter of electrode, and significantly increased when the electrode with a T-shape was employed. The electric field at the edge of water droplet is kept relatively large when the rod electrode with a large diameter or the T-shape electrode is employed. The present result can be explained by this effect, the change of local electric energy at the edge of the droplet.
