▎ 摘　　要

NOVELTY - The electrode (20) has multiple adsorption holes (203) and multiple ventilation passages (204) that are arranged in a base (202). The adsorption hole is arranged on adsorption end surface (205) of the base. The gas permeable passage communicates between the adsorption end surface and the surface. The number of the adsorption holes is greater than the number of the gas permeable channels. The electrode sheet arranged on the base is located in a middle portion of the base. The electrode sheet is located on a side of the base where the adsorption hole is arranged. The area of the base is larger than the area of the electrode sheet. USE - Graphene-based electrocardiographic electrode of electrocardiographic monitoring wearable device and electrocardiogram monitoring system (all claimed). ADVANTAGE - The occurrence of adverse reactions in the human body is reduced. The electrocardiogram electrode is made of graphene to reduce the interference of other signals, and the ECG signal extraction effect is better. DESCRIPTION OF DRAWING(S) - The drawing shows a cross sectional view of graphene-based electrocardiographic electrode.
