An investigation into the electromechanical performance of textile fabrics with conductive yarn elements for data transfer capabilities

Abstract

This paper investigates the electromechanical performance of textile fabric with conductive yarn elements for data transmission capabilities. Electromechanical experiments were conducted to evaluate the electrical response of copper yarn elements stitched axially to the textile fabric, while assessing the mechanical response of the system during tensile tests under axial loading. The results indicated that the yarn element exhibited low electricomechanical coupling below 1.5% strain, making it suitable for consistent electrical performance during low mechanical strain conditions. Computational models were also developed and correlated with the experimental results of the conductive yarn. The computational model was then expanded to investigate the effect of the braiding angle in the braiding system, providing insights into how these parameters influence the system’s performance. Overall, this research contributes valuable insights into the electromechanical behavior of textile fabric with conductive yarn elements, and presents a framework for optimizing data transfer capabilities in e-textiles and smart textile applications. The findings open opportunities for further advancements in the design and engineering of functional textiles for a wide range of applications.
