Zusammenfassung: | Textile strain sensors capable of monitoring human physiological signals and activities have great potential in health monitoring and sports. However, fabricating sensors with a wide sensing range, high sensitivity, robustness, and the capability for seamless integration into apparel remains challenging. In this work, a textile resistive strain sensor (TRSS) fabricated by selectively inlaying a conductive yarn, that is covered with water-repellent and antioxidative acrylic/copper complex fibers, into a highly elastic substrate via an industrialized knitting process is proposed. The conductive yarn is folded and compactly stacked to sense strains by changing contact resistance through contact separation of adjacent yarn sections in stretching. Owing to this folded structure, the TRSS has a wide sensing range (0–70%), high sensitivity (maximum gauge factor GF
