Stretchable textile-based friction nano-generator based on tubular spiral braided structure

The invention relates to a stretchable textile-based friction nano-generator based on a tubular spiral woven structure, and relates to the field of textiles. According to the stretchable textile-based friction nano-generator based on the tubular spiral woven structure, the superelasticity and the high flexibility of the stretchable textile-based friction nano-generator based on the tubular spiral woven structure are achieved through the large deformability of the tubular spiral woven structure and the elastic recovery performance of the elastic core yarn; when the first friction knitting yarn and the second friction knitting yarn are stretched and recovered, an electric signal can be generated by contact separation of the first friction knitting yarn and the second friction knitting yarn, and friction or contact separation with other materials is not needed at all; when external acting force such as touch and pressing is applied to the textile-based friction nano-generator, electric signals can be generated,
