Abstract

A capacitor comprising at least two electrodes separated from one another by an elastic dielectric formed of rubber and/or plastic for measuring forces acting upon one of the electrodes--the so-called measuring electrodes--by detecting the resultant change in capacitance. The dielectric in its unloaded state is pre-compressed and preferably possesses a number of hollow spaces.
