▎ 摘　　要

NOVELTY - A dry electrocardiogram electrode preparing method involves taking graphene and adding to dimethyl siloxane solution. The graphene is mixed in the dimethyl siloxane solution to obtain graphene and poly-dimethyl siloxane mixture. The propylene wafer is placed in a container. The metal snap fastener is arranged on the propylene wafer. The graphene and poly-dimethyl siloxane mixture is poured in the container. The graphene and poly-dimethyl siloxane mixture is dispersed for filling reserved space. The peeling off mold is formed to obtain the finished product. USE - Method for preparing dry electrocardiogram electrode. ADVANTAGE - The method enables preparing dry electrocardiogram electrode with good electrical conductivity, improved body surface biocompatibility, good flexibility and strong market potential. DETAILED DESCRIPTION - A dry electrocardiogram electrode preparing method involves taking graphene and adding to dimethyl siloxane solution. The graphene is mixed in the dimethyl siloxane solution to obtain graphene and poly-dimethyl siloxane mixture. The propylene wafer is placed in a container. The electrocardiogram measuring system is placed. The metal snap fastener is arranged on the propylene wafer. The graphene and poly-dimethyl siloxane mixture is poured in the container for carrying out heating process. The electrode chip main mold is separated. Propylene is extracted from the electrode chip main mold. The electrode chip main mold is fixed on a coater rotary disk. The graphene and poly-dimethyl siloxane mixture is dispersed for filling reserved space of the electrode piece main mold. The rotary coating process is carried out. The peeling off mold is formed to obtain the finished product on the graphene and poly-dimethyl siloxane mixture.
