This paper describes a new method for three-dimensional transportation of liquid droplets using EWOD (Electro Wetting on Dielectric). This method makes use of surface tension and electrostatic forces, which become dominant in microscale devices. The droplet transported on a vertical or upside down surface is affected by gravity force. In order to reduce the gravity effect, volume of water was reduced and shape and size of electrodes were changed. A water droplet was transported on a inclined plate, and the angle of inclination was changed from 10° to 360° by every 10°. The results show that water droplet can be transported on all inclined surfaces. Horizontal transportation of a droplet on a vertical surface was also made successfully.
