ABSTRACT:
A variable area capacitive transducer has two electrodes, and the surface of one electrode is treated to provide it with a thin-film dielectric layer. One of the two electrodes has an apex point nearer the other electrode than the remainder of the electrode surface. As a force is applied to the deformable one of the two electrodes, there is a change in the effective contact area between the electrodes and a resultant change in capacitance. An electrical circuit is disclosed for translating this capacitance change into a d-c voltage change. Temperature compensation is provided for the transducer assembly.
