  • Patent number: 11660029
    Abstract: Provided in the present invention are a flexible electrochemical electrode, a subcutaneous continuous glucose monitoring sensor equipped with the electrochemical electrode, and a preparation method thereof. The electrode directly uses gold layers on both sides of a chemically plated film, respectively as a working electrode and a reference-counter electrode, so as to form an electrochemical two-electrode system. Petaloid platinum nanoparticles are electrodeposited on a surface of the configured working electrode as a catalytic layer; a carbon nanotube/Nafion mesh layer functions as an anti-interference layer, and is formed thereon with an enzyme biochemical sensitive layer by means of electrostatic adsorption, after crosslinking and curing in glutaraldehyde, polyurethane mass transfer is coated to limit a protection layer, so as to prepare a flexible continuous glucose monitoring sensor.
