Wearable continuous blood glucose monitoring equipment based on antifouling coating

The invention discloses wearable continuous blood glucose monitoring equipment based on an antifouling coating, and belongs to the technical field of electrochemical sensors. The blood glucose biosensor consists of a sensor shell, a PCB (Printed Circuit Board) circuit, a sensor microneedle and a blood glucose biosensor electrode module with an antifouling coating at the front end of a working electrode, the PCB circuit is composed of a sensor battery module, a microcontroller unit integrated on an Arduino nano development board and comprising an analog-to-digital converter and a system on chip, a Bluetooth module and a mobile phone terminal APP, and the antifouling coating is of a sandwich structure composed of a protective layer, a glucose oxidase layer and a modified sulfonate-based polyurethane layer. The antifouling coating provided by the invention can effectively solve the problems of detection signal offset, delay and attenuation caused by electrode loss in a long-term monitoring process due to non-spe
