Scalable production of stretchable conductive fibers for textile electronics

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.
