Abstract: When a positive voltage of V1 is applied to a drive capacitor with a braking voltage V2 at 0V, a moveable electrode moves toward the drive electrode, and a capacitance C of a tunable capacitor becomes smaller. When the braking voltage V2 is applied a lower portion brake electrode of the brake capacitor moves in a horizontal direction, such that the inter electrode separation distance between an upper portion brake electrode and the lower portion brake electrode becomes 0 ?m. The moveable electrode configured integrally formed with the lower portion brake electrode also moves in the horizontal direction, and the inter electrode separation distance between the moveable electrode and a fixed electrode becomes 0 ?m. Since the two electrodes make contact with each other with a dielectric layer interposed therebetween, the position of the moveable electrode can be stably maintained by frictional force between the electrodes.
