NOVELTY - Preparing an elastic strain sensing material with a wrinkled structure comprises (1) preparing the pretreatment solution, (2) soaking the stretchable elastic substrate in the pretreatment solution to fully swell the stretchable elastic substrate, (3) taking the swollen stretchable elastic substrate out of the pretreatment solution and dry it to obtain a stretchable elastic substrate with a sticky surface, (4) preparing a conductive dispersion liquid, (5) adding styrene-based thermoplastic elastomers (TPE) material to the configured conductive dispersion and mix thoroughly to obtain conductive paste, (6) pre-stretching the dried stretchable elastic substrate, and (7) soaking the pre-stretched stretchable elastic substrate in the configured conductive slurry, taking out after soaking, drying at room temperature, repeating the process of immersing in conductive paste many times and taking it out to dry to form a conductive film on the stretchable elastic substrate. USE - The method is useful for preparing an elastic strain sensing material with a wrinkled structure. ADVANTAGE - The composite fiber has an elastic base and a conductive pleated structure, which can realize both conductive and stretching functions at the same time, and has strain sensing characteristics. The method: is simple, economical, and environmentally friendly; has controlled the pre-stretching ratio and the number of soaking times of the elastic substrate, and controlled the fold shape and size, and controlled strain sensing performance.
