A scaled-up fiber wet-spinning production of electrically conductive and highly stretchable PU/PEDOT:PSS fibers is demonstrated for the first time. The possess mechanical properties appropriate knitting various textile structures. knitted textiles exhibit strain sensing that were dependent upon number used in knitting. show sensitivity (as measured by gauge factor) increases with deployed. stable sensor response was observed when four co-knitted a commercial Spandex yarn. can distinguish different magnitudes applied cyclically repeatable responses at strains up to 160%. When conjunction wireless transmitter, responded well magnitude bending deformations, demonstrating potential remote applications. feasibility an all-polymeric wearable knee sleeve prototype application personal training rehabilitation following injury.
