A novel self-centered variable focus liquid lens based on electrowetting-on-dielectric (EWOD) is presented, which consists of a glass plate coated with two transparent layers of conductive ITO film and hydrophobic dielectric film, a conical tube partly covered with hydrophobic film positioned with a gap above the glass plate and a water droplet.
