Conductive rubber materials for pressure sensors

Abstract

Over the years, many researchers have studied the resistivity of conductive composites as a function of pressure. However, the use of these materials as pressure sensors could not be supported because of the inability to control the sudden resistivity drop and large variation in successive resistivity measurements. This paper discusses the results relating to the fabrication and assessment of some electrical and mechanical properties of carbon black filled silicons rubber composites as pressure sensors for practical applications.
