Capacitor sensor capable of controlling sensitivity

摘要

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.

主权项

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.
