外文摘要：The large-scale three-and two-dimensional structures of traditional textile-based flexible capacitive sensors, along with their pressure-dominated sensing mechanisms and monitoring applications, have constrained the development of these sensors in the field of human physiological signal monitoring. To develop stretchable onedimensional flexible capacitive sensors (SOFCS) with broader application fields, more flexible structural designs, and enhanced implantability, this study employed an improved multi-needle water bath electrospinning method to prepare polyacrylonitrile (PAN) nanofiber-coated silver-plated nylon (SPN) core-spun yarns (NFCY). Utilizing these yarns as raw materials (serving as both electrodes and dielectric layers), a stretchable one-dimensional flexible capacitive sensor achieving a strain of up to 70 % was constructed and applied for monitoring human motion and vital signs. Research results demonstrate that electrode composition, carrier diameter, and electrode winding density significantly affect sensor performance. The optimized sensor exhibits high sensitivity (maximum GF 2.04), maintains stable capacitive responses under varying strains and stretching speeds, demonstrates strong robustness to deformation velocity, and shows excellent durability and repeatability. This sensor can effectively monitor joint movements, posture, respiration, and speech signals, maintaining reliable sensing performance when integrated into garments. It demonstrates significant potential for development in the field of electronic textiles for health monitoring applications.
