ABSTRACT:
A sensor array includes a number of discrete elements each comprising a dielectric body and two electrodes. Dielectric body has an annular skirt and the electrodes define an annular gap in which an end portion of the skirt is located. Body is displaced relative to the electrodes upon application of pressure thereto, causing the skirt to further penetrate the gap and cause a detectable change in capacitance of the electrodes, related to the magnitude of the applied pressure. The dielectric bodies are supported by a common, resilient sheet which returns the bodies to a rest position when pressure is removed.
