1. A device for varying capacitance, comprising:

  • a first dielectric (54) and a second dielectric (55), the first dielectric (54) and the second dielectric (55) being arranged in parallel and spaced apart from each other to form an isolation layer (58) therebetween;

    a first electrode (56) and a second electrode (57), the first electrode (56) and the second electrode are connected to the first dielectric (54) and the second dielectric (55) at the same one end face of the first dielectric (54) and the second dielectric (55), respectively,an elastic conductive pad (52) being disposed at the other end face opposite to the one end face; and

    a gasket (53) being disposed between the first dielectric (54) and the second dielectric (55) and the elastic conductive pad (52).
