This study aims to evaluate the durability of a fiber-based module subjected torepeated stretch/release cyclic deformation. The fiber-based module connects an LED anda conductive yarn via the embroidery technique. For this purpose, different stitch patternparameters, such as the stitch shape, length, and spacing, were applied, and the resistancechanges were measured according to repeated tensile deformations. Among the threestitch patterns (i.e., straight, zigzag, and wavy), the zigzag pattern showed a resistance of30.7 Ω/cm per unit embroidery length, and had the lowest resistance change even afterrepeated stretching recovery deformations. Based on the experimental results, a fiberbasedmodule was manufactured by connecting an LED lamp to a zigzag pattern with aresistance of 11.9 Ω/cm and resistance change of approximately 18%. During elastic deformation,the LED was operated for 1200 cycles. The results indicate the potential applicationsin the production of smart clothing that requires elastic recovery.
