Previous studies of polyisoprene nanostructured carbon black composites (PNCBC) have proven that this material could be used to produce cheap pressure, impact or vibration detection units – sensors [1]. Depending on the carbon black (CB) concentration and filler dispersing methods PNCBC reveals more or less distinctive piezoresistive properties as well as good electrical conductivity [2]. In this article we try to elaborate completely hyperelastic pressure sensitive mat (CHPSM) capable of large scale pressure mapping using layered composite approach. The CHPSM were made from raw PNCBC compositions with variable concentrations of electroconductive carbon black. Each element of CHPSM was semi-vulcanized separately so it could maintain its shape during final vulcanization when these elements were cured together to form a uniform sensor. The CHPSM consists of 6 separate piezoresistive elements with hyperelastic electrodes incorporated into non-conductive natural polyisoprene rubber shell. Dimensions of the elaborated CHPSM are 100x70x5 mm but they can be easily tailored for a specific requirement.
