▎ 摘　　要

NOVELTY - The electrode has a flexible substrate whose surface is provided with a convex part and a metal electrode i.e. copper electrode. A metal seed layer i.e. chromium/copper seed layer, is arranged between the metal electrode and the flexible substrate that is made of polydimethylsiloxane, polyimide or parylene. A coronary array is arranged corresponding to the spaced convex part. A graphite alkene conductive layer is formed between the metal seed layer and the metal electrode. An electrode lead wire is connected with the metal electrode. USE - Graphene-based flexible coronary heart electric electrode. ADVANTAGE - The electrode is soft and flexible to use, and increases contact area between the metal electrode and the flexible substrate, increases the signal to noise ratio and improves the stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene-based flexible coronary heart electric electrode preparation method. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a graphene-based flexible coronary heart electric electrode.
