Abstract: The market size of electronic textiles is expanding daily and they have been widely applied in various fields such as medicine military sports and home furnishing.As emerging functional textile products that integrate the characteristics of electronic devices and textile materials electronic textiles not only retain the comfort and popularity of traditional textiles but also possess the interconnectivity of electronic products.In electronic textile systems signal transmission is a crucial aspect encompassing both wireless and wired transmission methods.Although wireless transmission offers greater flexibility wired transmission remains an indispensable transmission method for the interconnection between electronic textiles and their proximal modules due to its stability reliability and resistance to interference.To realize the flexibility and integration of textile transmission lines researchers are committed to developing ideal transmission lines for electronic textiles that balance comfort with excellent signal transmission performance.Conventional low-frequency transmission lines such as metal twisted pairs and electrical wires are rigid in texture and difficult to meet the requirements of new electronic garments for transmission lines.Therefore researchers are focused on developing flexible textile transmission lines by carefully selecting conductor materials optimizing structural designs and continuously innovating preparation techniques for conductive wires.Methods such as spinning coating or compositing are employed to prepare conductive wires which are then integrated into textile garments through embroidery sewing printing techniques or directly by weaving or knitting thereby achieving miniaturization of the transmission lines and integration with textiles.At present substantial progress has been made in textile transmission lines for electronic textiles but several challenges remain.Firstly transmission lines prepared by existing technologies have certain defects in structure and their transmission performance in terms of stability and reliability still lags behind widely used standard transmission lines necessitating further optimization of the preparation process.Secondly there are numerous and diverse testing methods evaluation indexes and standards for transmission line performance necessitating the establishment of unified evaluation criteria.Lastly current research on textile transmission lines mostly focuses on single functions and the development of integrated functional transmission lines tailored for different application scenarios will become one of the research hotspots.As single-function electronic textiles transition towards multi-function ones the number of functional electronic devices increases necessitating the development of multi-channel signal transmission modes.It is necessary to reduce the number of wires simplify circuit layout enhance the aesthetic appeal and comfort of garments and meet the diverse needs of various application scenarios.Therefore future research on transmission lines for electronic textiles will strive to address existing challenges and promote the functional integration and integration development of electronic textiles.This paper reviews the classification preparation techniques performance testing methods and evaluation indexes of textile transmission lines for electronic textiles providing technical reference for the design and preparation of signal transmission lines and outlining the prospects for future development.
