However, the shape of the sole and walking habits of each individual are different due to individual differences. Therefore, how to manufacture personalized insoles at low cost and large scale quickly becomes a challenging task, and intelligent high polymer materials refer to a class of high polymer materials which can sense external environment changes and respond quickly. Currently, two main types of intelligent polymer materials are velocity-sensitive intelligent Shear Thickening Gel (STG) and Shape Memory Polymer (SMP). SMP is divided into thermoplastic type and thermosetting type, and the principle of generating shape memory function is the same, i.e. the product with initial shape changes its initial shape and fixes under a certain condition, and then can recover its initial shape by external condition (light, electricity, heat, etc.) stimulation, so as to complete the cycle of 'memory initial state-fixed deformation-recovery initial state'. Currently, the SMP mainly developed is a temperature sensitive shape memory polymer material.
If granted utility model patent CN212368456U introduced a multi-hardness material shock-absorbing insole with memory function, which mainly increases comfort by attaching slow-resilience memory sponge on the middle layer, but it does not have the intelligence of "remember initial state-fixed deformation-recovery initial state". For example, the granted utility model patent CN211510731U of the li ning (china) sports goods limited company adopts at least one of the thermoplastic shape memory materials including polycaprolactone and thermoplastic polyurethane as the supporting layer of the insole, when switching different shoes or sports modes, the insole needs to be heated to 40-60 ℃ for softening, then the insole is stepped on by feet and kept bending knee for shaping, and meanwhile, in order to provide arch support, the insole needs to be shaped into an arc-shaped bulge. Meanwhile, the manufacturing process of the insole needs to be jointed for many times.
