Abstract
A pressure sensitive conductor comprising an elastomer containing from 3 to 40% by volume of electrically conductive magnetic particles, which particles are dispersed in the elastomer so that high-sensitivity pressure sensitive conductor portions and insulator portions or low-sensitivity pressure sensitive conductor portions are both present therein. A method of manufacturing the pressure sensitive conductor comprises forming a sheet of a mixture containing electrically conductive magnetic particles in an elastomer, and subjecting the sheet to the action of magnetic fields before or during cross linking, thereby allowing the conductive magnetic particles to be uniformly dispersed in the sheet in a selected pattern.
