摘要： A high-stretchable high-sensitive flexible force-sensitive sensing fiber and a preparation method therefor comprising the specific preparation method is as follows: uniformly and synergistically dispersing a one-dimensional (1D) nanowire/nanotube and a two-dimensional (2D) conductive sheet layer in a thermoplastic elastomer solution; formulating a uniform dispersion solution of a certain concentration; and using a wet spinning process to prepare an elastic composite fiber with a highly oriented 1D/2D hybrid network. The above-described composite fiber is placed in a metal precursor solution to fully swell, and then placed in reductive steam for reduction, to reduce metal precursors to zero-dimensional (0D) metal nanoparticles, thereby preparing a flexible force-sensitive sensing fiber based on a 0D/1D/2D three-dimensional collaborative network.
