US 4266263 A 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. 1. A capacitor comprising: a pair of
separate electrodes, one of which electrodes defines a measuring
electrode; an elastic dielectric interposed between said pair of
electrodes and having a plurality of air containing chambers,
for separating said electrodes from one another; said elastic
dielectric being formed from a material selected from the group
consisting of rubber, plastic and mixtures, thereof; said
electrodes serving for the measurment of forces acting upon said
measuring electrode by detecting resultant capacitance changes;
and said plurality of air containing chambers having an air
pressure that is less than no
