Abstract:
1. A capacitor sensor capable of adjusting sensitivity, comprising: a capacitor made of a dielectric material, with a unique permittivity, as an incompressible synthetic dielectric elastomer and having two surfaces that are opposite to each other; two electrodes respectively disposed on the two surfaces of the capacitor, each of the two electrodes formed in a 2-dimensional shape whose width tapers off in one direction, the two electrodes tapering in opposite directions, and a degree to which each of the electrodes tapers being variable; and a capacitance measurer connected to each of the two electrodes, wherein: the two electrodes partially overlap each other as seen from above, and when a shear force is applied to the capacitor sensor, the overlapping area of the electrodes changes and the capacitance measurer determines the change of the overlapping area by measuring the change in capacitance resulting from the change in the overlapping area of the electrodes.
