    摘要： A varifocal optical device is provided. The varifocal optical device includes an optical lens, an actuator unit connected with the optical lens and having two areas that are bending-deformed in opposite directions to each other when a voltage is applied thereto, and a supporting unit to support the actuator unit, so that a focus of the optical lens is varied by the bending deformation when the voltage is applied to the actuator unit. Thereby, a driving displacement of the varifocal optical lens can be maximized.

    摘要： A variable-focus liquid lens is provided. The liquid lens includes a membrane and a fluid. The membrane is made of a transparent elastomer, and the fluid fills a predetermined space to contact at least a lens surface of the membrane. The membrane and the fluid are respectively made of materials repulsive to each other, for example, hydrophilic and hydrophobic materials or oleophilic and oleophobic materials. Accordingly, a repulsive force between the fluid and the membrane can prevent the absorption or leaking of the fluid into/through the membrane.
