▎ 摘　　要

NOVELTY - The sensing needle has a stainless steel acupuncture needle (1). A front end of upper surface of the acupuncture needle is covered with a gold film (3) by electrochemical deposition. A graphene film (4) for oxidation reduction covers the surface of the gold film by electrochemical deposition on the tip portion of the needle. An insulating layer (2) covers and seals the upper rod portion of acupuncture needle which is not covered by the gold film and the graphene film. USE - Nanometer sensing needle used for acupuncture medical treatment. ADVANTAGE - Provides good conductivity, high detection sensitivity, good stability, and greater linear response range. Manufacturing is made simple and convenient. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preparation method of a nanometer sensing needle. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic cross-sectional view of a nanometer sensing needle.
