NOVELTY - A graphene electrocardiogram dry electrode comprises a thin layer of graphene, which is coated on a carbon fiber formed dry electrode to increase its electrical conductivity and abrasion resistance. USE - The graphene electrocardiogram dry electrode is useful for electrocardiogram detection. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the graphene electrocardiogram dry electrode, which involves: (1) preparing a graphene aqueous solution or an organic solvent solution; (2) coating the graphene solution on the carbon fiber forming dry electrode; and (3) carbonizing the graphene film coated on the formed electrode by roasting or hot pressing.
