Abstract: An elastomeric composition comprising a non-conductive elastomer having dispersed therein (i) elastomer particles, 10-300 .mu.m in diameter, (ii) conductive particles, 1-40 .mu.m in diameter, and (iii) hollow and elastic microspheres, 10-50 .mu.m in particle diameter, non-conductive when not deformed, becomes conductive when deformed by compression, extension, torsion or bending. The elastomeric composition may also have dispersed therein insulating and elastic fibers less than 100 yarn denier thick and 3-6 mm in length.

Abstract: A pressure sensitive sensor in which a pressure detecting convex portion is formed on the surface of a pressure-sensitive and conductive elastomer sheet, and an electrode is arranged on the reverse side of the pressure detecting convex portion for making it possible to detect a pressure acting in the direction in parallel or in the oblique direction with a slight angle with respect to the surface of a pressure-sensitive and conductive elastomer component. In addition, for obtaining a high detection density, a contact is made up with a face-defined body defining a pressure face, and a contacting convex portion is made to protrude from the face-defined body, where the contact is resiliently supported onto the pressure-sensitive elastomer sheet.
