Abstract
An electrocardiography (ECG) electrode includes an electrode substrate and a doped graphite-like carbon (GLC) film located on an outer surface of the electrode substrate. The doped GLC film includes GLC, and first nano-crystals and second nano-crystals that are embedded in the GLC. The first nano-crystal includes a weak carbon-bonding element. The weak carbon-bonding element has a part that exists in a form of a metallic elementary substance. The first nano-crystal includes a columnar structure. The columnar structure extends in a thickness direction of the doped GLC film. The second nano-crystal includes a strong carbon-bonding element. The strong carbon-bonding element bonds with the carbon element in the GLC through a chemical bond. The second nano-crystals are distributed between adjacent and spaced columnar structures.
