Stretchable conductive fibers are key building blocks for constructing textile electronics. In this Preview, we highlight the scalable production of stretchable conductive fibers based on multimaterial thermal drawing and chemical deposition. The resulting fibers exhibit initial electrical conductivities up to 4,415 S/cm while retaining more than 500% stretchability. They can be further made into multifilaments, driving the development of textile electronics toward real-world applications.

Stretchable and conductive fibers fabricated by a continuous method for wearable devicesMa et al.Cell Reports Physical ScienceFebruary 21, 2023In BriefMa et al. develop a continuous approach for fabricating stretchable and conductive fibers, which are suitable for being twisted into textile yarns, woven and knitted into textile fabrics, or braided and stitched onto textile structures. These textiles can be assembled into breathable and washable devices for wearable electronic applications. Full-Text PDF Open Access
