Abstract: A variable capacitor is disclosed. The variable capacitor includes a multi-layer ceramic capacitor member, and a capacitance varying mechanism. The multi-layer ceramic capacitor member includes one or two external electrode(s), a ceramic dielectric, and a plurality of electrode layers positioned inside the ceramic dielectric. The capacitance varying mechanism includes an electrical conductor positioned aside and approximate to the ceramic dielectric. The electrical conductor is deformable responsive to a pressure applied thereon, and an area of the electrical conductor in contact with the ceramic dielectric varies in accordance with the pressure, thus varying a capacitance value between the external electrode(s) and the electrical conductor. In general, the external electrode(s) of the multi-layer ceramic capacitor member serve(s) as fixed electrode(s) of the variable capacitor.

Abstract: A capacitance-variable pressure sensor is disclosed. The capacitance-variable pressure sensor includes a double layer flexible circuit board, a multi-layer ceramic capacitor, and a soft conductive pad. The multi-layer ceramic capacitor is positioned in adjacent to the soft conductive pad. The double layer flexible circuit board is configured with a through hole or a notch, and is positioned between the multi-layer ceramic capacitor and the soft conductive pad. The multi-layer ceramic capacitor is positioned above the through hole or notch, and the soft conductive pad is positioned under the through hole or notch. The multi-layer ceramic capacitor includes a first member and a second member. The first member includes an external electrode or a plurality of external electrodes. The second member includes a ceramic dielectric, and a plurality of internal electrode layers disposed inside the ceramic dielectric. Each external electrode is connected to internal electrode layers.
