Abstract: The present disclosure mainly relates to a nonlinear resistance strain sensor. The nonlinear resistance strain sensor includes an elastic substrate and a plurality of conductive substances. The plurality of conductive substances are uniformly distributed on the elastic substrate. When the elastic substrate is pulled, the length thereof corresponding increases, and the density of the plurality of conductive substances on the elastic substrate decreases, thereby changing the overall resistance thereof. In the above manner, the nonlinear resistance strain sensor of the present disclosure has nonlinear and high-sensitivity resistance strain performance.
