外文摘要：To prepare a highly stable, flexible sensor for body motion and vital sign monitoring, a conductive warp-knitted fabric (CWKF) with a two-bar tricot structure was prepared by in situ polymerization, and then a waterborne polyurethane-coated conductive warp-knitted fabric (WPU/CWKF) was prepared using a simple dip-and-dry method. The structure and properties of both CWKF and WPU/CWKF were analyzed, their strain-resistance sensing properties were investigated, and their application in body motion monitoring was discussed. The results indicate that conductive treatment of in situ polymerization can create polyester warp-knitted fabric with good electrical conductivity, with a resistivity of approximately 5 Ω·cm, which is approximately 11 orders of magnitude lower than that of the polyester fabric. After coating with WPU, the resistivity of the WPU/CKWF increased to approximately 40 Ω·cm. The modulus and hardness of WPU/CKWF were improved when compared to CWKF. Both CKWF and WPU/CKWF showed good strain-resistance sensing performance, but CWKF was more sensitive than WPU/CKWF, whereas WPU/CKWF was more stable than CWKF. Both the CWKF and WPU/CKWF sensors could monitor body motion in real time. Similar to their base materials, the CWKF sensor demonstrated a higher sensitivity for human movement monitoring, whereas the WPU/CKWF sensor exhibited higher stability. ? 2023, The Authors.
