Polyisoprene - nanostructured carbon composite (PNCC) is often treated as a prospective multifunctional sensor material [1]. It has unique property to rapidly and reversibly change its electrical conductivity under applied external strain or pressure. More likely – under all types of external deformation it has a remarkable as well as reversible piezoresistive effect. To obtain PNCC, certain conditions must be taken into account, such as hyper elastic polymer matrix and high structure conductive carbon filler must be chosen. The previous research approved that unique properties are provided only after the composite is vulcanized [2]. In our work we present latest result on designing, preparing and obtaining the PNCC with necessary properties, as well our efforts on practical application of such material. The dependence of PNCC sensing properties on vulcanization time, pressure as well as filler type and concentration is evaluated. The completely-hyper elastic multi layer structural design is proposed to be used as a sensing element.
