NOVELTY - The utility model claims an electrocardio-electrode and electrocardio-electrode assembly. the electrocardiogram electrode comprises a substrate layer and a graphene layer set on the substrate layer; the graphene layer comprises a graphene film layer and a graphene foam layer orderly laminated on the substrate layer; the graphene film layer is used for electrically connecting with the collector of the electrocardiograph; the graphene foam layer is used for bonding skin. The electrocardio-electrode sheet is made of graphene material, has good conductivity, at the same time, has good biological compatibility. on the other hand, using graphene foam layer and skin contact with good air permeability, and capable of releasing and relieving the external pressure, so the electrocardiogram electrode has good flexibility, which greatly increases the comfort of the user, and can well adhere to the skin, ensures the stable collection of the electrocardiogram signal
