    Abstract: A tunable capacitor using an electrowetting phenomenon includes a first electrode; a second electrode which is spaced apart from the first electrode and faces the first electrode; a fluidic channel which is disposed between the first electrode and the second electrode; a first insulating layer which is disposed between the first electrode and the fluidic channel; and a conductive fluid which is disposed in the fluidic channel and moves along the fluidic channel when a direct current (DC) potential difference occurs between the first and second electrodes. Accordingly, it is possible to fabricate the tunable capacitor with the simplified fabrication process, good reliability and durability, and no restriction on the tuning range.

    Abstract: 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.

    Abstract: A vari-focal fluidic lens is provided. The fluidic lens includes a frame, an first membrane, a second membrane, and an optical fluid. The frame defines an inner space of the fluidic lens including a driving portion and a lens portion that are connected to each other. The elastic membrane is attached to one side of the frame to cover at least the lens portion. The second membrane is attached to an opposite side of the frame to cover at least the driving portion and is deformable in response to temperature change to vary a volume of the inner space. Optical fluid is contained in the inner space.
