Study on preparation of conductive yarn and its application in wearable electronics

Abstract

With the development of electronic information technology and people's pursuit of a convenient life, intelligent and flexible wearable electronics have received more and more attention, and have achieved relevant research results. Conductive yarn, as the most basic flexible conductive textile material, the conductive yarn is widely used in intelligent wearable products. However, traditional textile materials are usually insulating materials and do not directly form conductive yarns and smart wearable products. This paper focuses on the preparation methods of conductive yarns by coating, spinning, and in situ polymerization, and the application research progress in wearable strain sensors, wearable supercapacitors and wearable electric heating devices. In addition, the convenience, comfort, washability and sensitivity required for wearable electronics are proposed to further optimise the flexible sensitivity and durability of conductive yarns and methods of combining textile materials with conductive materials are the main development directions for wearable flexible smart products.
