▎ 摘　　要

NOVELTY - A sensing material comprises carbon black raw materials, graphene raw materials and rubber compounds. The sensing material is present in contact with living things, and is prepared by mixing the carbon black raw material, the graphene raw material and the rubber compound. USE - Sensing material is useful in bio-contactable unit for sensing physiological parameters (claimed). DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) the method for preparing unit present in contact with living things, which involves providing a wearing member, providing a carbon black raw material, a graphene raw material, and a rubber compound, mixing the carbon black raw material, the graphene raw material and the rubber compound to form a mixed colloid, coating the mixed colloid on the wearing member, drying, repeating the coating and drying steps until a suitable number of coating layers is reached to form a processed wearing portion, and baking processed wearing portion to form the nano-conductive, bio-contactable unit; and (2) a bio-contactable unit for sensing physiological parameters, which comprises a nanocarbon layer that transmits a physiological signal in response to the physiological parameter and a protective layer that protects the nanocarbon layer.
