▎ 摘　　要

NOVELTY - Medical sensor comprises a sensor body (1), a functional groove provided with the center of the surface of the sensor body, a super-hydrophilic layer (21) and a hydrophobic anti-corrosion layer (22) sequentially coated with the bottom of the functional groove from top to bottom, two electrode grooves symmetrically arranged on both sides of the functional groove, electrode (31) and electrode leads are arranged in the electrode grooves, and a conductive layer (32) provided with the surface of the electrode, where the conductive layer is in contact with the edge of the super-hydrophilic layer, the conductive layer is made of graphene oxide material, the super-hydrophilic layer is made of modified acrylic resin, the modified acrylic resin is prepared by mixing modified silica composite microspheres and acrylic resin, the hydrophobic anticorrosive layer is made of modified epoxy resin, and the modified epoxy resin is prepared by mixing silica nanospheres with epoxy resin. USE - Medical sensor. ADVANTAGE - The sensor gas long-term super-hydrophilic properties by redesigning the structure and material of the sensor. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the medical sensor. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of the medical sensor.
