摘要： A pressure sensor utilizing an extension type conductive elastomer that exhibits a decrease in its electrical resistance responsive to an extension applied thereto. Like sheets of the conductive elastomer 3 and an electrically insulative elastomer 2 are overlaid and sandwiched between supporting members within a housing 1. The housing and each supporting members are preferably cylindrical or ring shaped, which conductive elastomer has a pair of spaced electrodes 5,6 electrically connected thereto at its periphery. The periphery of the electrically insulative elastomer is squeezed continuously in a circle between the supporting members, while the periphery of the conductive elastomer is squeezed therebetween discontinuously in the sections between the electrodes. When a pressure is applied to the contacting elastomers, they will be convexedly deformed both experiencing an extension in their portions not being squeezed together. The applied pressure can be sensed as a change in electrical resistance across the electrodes.
