NOVELTY - Preparing a graphene-based segmented detection sensor involves cleaning the reaction vessel with deionized water and then drying it, adding 3 to 5 layers of graphene powder and dispersant to deionized water at a ratio of 10:1, and using ultrasonic technology to disperse uniformly to obtain graphene/ Deionized aqueous solution. The reaction vessel is washed with deionized water and dried, and 3 to 5 layers of graphene powder and dispersant are added to N,N-dimethylformamide (DMF) in a ratio of 10:1 and dispersed uniformly by ultrasonic technology to obtain a graphene/DMF solution, and then add the spandex (PU) solution dropwise to the graphene/DMF solution to obtain a mixed solution. A magneton is put into the mixed solution, seal the mixed solution, and stirred with a magneton stirring device to obtain a graphene/PU solution. USE - Method for preparing segmented detection sensor based on graphene. ADVANTAGE - The method enables preparing the segmented detection sensor in a simple manner. DETAILED DESCRIPTION - Preparing a graphene-based segmented detection sensor involves cleaning the reaction vessel with deionized water and then drying it, adding 3 to 5 layers of graphene powder and dispersant to deionized water at a ratio of 10:1, and using ultrasonic technology to disperse uniformly to obtain graphene/ Deionized aqueous solution. The reaction vessel is washed with deionized water and dried, and 3 to 5 layers of graphene powder and dispersant are added to N,N-dimethylformamide (DMF) in a ratio of 10:1 and dispersed uniformly by ultrasonic technology to obtain a graphene/DMF solution, and then add the spandex (PU) solution dropwise to the graphene/DMF solution to obtain a mixed solution. A magneton is put into the mixed solution, seal the mixed solution, and stirred with a magneton stirring device to obtain a graphene/PU solution. The spandex monofilament is immersed in the graphene/deionized aqueous solution and taken it out and put it in an oven vertically for drying, immersed and dried it multiple times, and immersed it for the last time 2 in the graphene/PU solution, taken it out and put it in an oven vertically to dry to obtain a graphene sensor. The conductive copper wire with an insulating layer is used as the core yarn, and the outer layer is covered with silk to obtain a silk wire. The graphene sensor is used as the core yarn, and used a spinning frame to wrap a multiple silk wires at one end of each silk wire Scrape off the insulating layer and fixed it with the graphene sensor with conductive silver glue. The other end is drawn out after the graphene sensor is wrapped by a silk wire, and the insulation layer at the end of the drawn silk wire is scraped off as a measurement point to facilitate electrical signal detection. The detection of every two measuring points is equivalent to the segmented detection sensing section formed by the corresponding fixed points. A segmented detection sensor with the outermost layer made of silk wires, the middle layer made of graphene, and the innermost layer made of spandex monofilament.
