Preparation and Characteristics of Embroidered Circuit Board Using Conductive Yarns for e-Textile Applications

This study aims to evaluate the durability of a fiber-based module subjected to repeated stretch/release cyclic deformation. The fiber-based module connects an LED and a conductive yarn via the embroidery technique. For this purpose, different stitch pattern parameters, such as the stitch shape, length, and spacing, were applied, and the resistance changes were measured according to repeated tensile deformations. Among the three stitch patterns (i.e., straight, zigzag, and wavy), the zigzag pattern showed a resistance of 30.7 Ω/cm per unit embroidery length, and had the lowest resistance change even after repeated stretching recovery deformations. Based on the experimental results, a fiberbased module was manufactured by connecting an LED lamp to a zigzag pattern with a resistance 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 applications in the production of smart clothing that requires elastic recovery.
