More specifically, in the working principle of the resistance wire 3, the resistance wire 3 is an elastic resistance wire, and is formed by polymerizing a polymer elastic material doped with a small amount of conductive particles through a vulcanization reaction. The high molecular polymer tightly restrains the conductive particles between the chain structures, the conductive particles are mutually contacted to form a chain conductive path, and the resistance value of the chain conductive path is a constant resistance value under a natural no-external-force state; when the resistance of the elastic resistance wire is stretched by external force in the length direction, the contact impedance among the conductive particles changes, so that the resistance value of the whole elastic resistance wire changes. In a certain deformation range, when the elastic resistance wire is stretched, the wire diameter of the elastic resistance wire is reduced, the conductive particles are extruded, the contact impedance among the conductive particles is reduced, and the overall resistance of the elastic resistance wire is reduced; when the elastic resistance wire is deformed and restored, the wire diameter is restored, the gaps among the conductive particles are enlarged, the contact impedance is enlarged, and the integral resistance value of the elastic resistance wire is enlarged.
