Abstract: ABSTRACT In recent years, smart textiles have shown broad prospects in the fields of medical health, sports monitoring, military protection and daily wear. However, the development of smart textiles still faces many challenges such as poor sensing performance and flexibility, making it difficult to meet practical application requirements. Highly elastic PY (polyurethane yarn) was used as the core layer material, and 8‐spindle SCNY (silver‐plated nylon yarn) was used as the outer layer. Through a precision winding process, a spiral‐woven sensor wire was successfully prepared. The effects of different twisting degrees on the mechanical and electrical properties of the wire were systematically investigated. Experimental results indicate that at a twist rate of 583 r/m, the yarn exhibits favorable strain‐sensing properties alongside excellent extensibility and electrical performance. The yarn reached a uniform temperature of 93.6°C at 1.25 V. In addition, the sensing yarn has a stable conductive network, and the temperature changes dynamically with strain during stretching, demonstrating the potential for dynamic temperature monitoring.
