The invention discloses a fabric sensor with negative piezoresistive effect and its application. An elastic knitted base cloth is selected as a base material, which is immersed in a dispersion liquid of a graphene-containing conductive material. , repeat the above operation one or more times; then reduce by hydrazine hydrate, wash and dry to obtain a coated composite fabric sensor; set at least two electrodes on the fabric, and connect the external current through conductive silver glue, aluminum foil, copper wire, etc. The source is connected to the voltage measuring instrument, and the strain sensing with negative piezoresistive effect is realized through its characterization of the piezoresistive effect of strain such as stretching, stab pressure, torsion, and swing. The fabric sensor is simple in process, easy to operate, low in production cost, stable in function, and has good scientific value and benefit prospects. . |
