First Claim
Patent Images
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, andwhen a shear force is applied to the capacitor sensor, the overlapping area of the electrodes changes, and the capacitance measurer measures the change of the overlapping area.

Abstract
There is provided a capacitor sensor capable of controlling sensitivity, wherein the capacitor sensor measures the magnitude and direction of a shear force applied to the sensor, as well as the magnitude of a normal force applied on the surface of the sensor, and consists of a single cell including a pattern electrode capable of varying its shape to control the sensitivity of the sensor.
