Stretchable Optical Fibers: Threads for Strain‐Sensitive Textiles

Stretchable Optical Fibers: Threads for Strain‐Sensitive Textiles Soft, stretchable, sewable, and strain‐sensitive optical fibers are reported. Intrinsically stretchable optical waveguides capable of >100% strain are formed by coating a commercially available elastic urethane fiber (“Stretch Magic”) with a silicone cladding having a lower refractive index. These 1–2 mm diameter fibers can be attached to textiles using a sewing machine. Because the attaching threads create microbends in the fiber, the sewn fibers are prestrained for monotonic intensity‐versus‐strain behavior. Installed in a stretchable piece of athletic tape, they detect strains originating from changing muscle shapes during weight‐bearing activity. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Advanced Materials Technologies Wiley

Abstract

Soft, stretchable, sewable, and strain‐sensitive optical fibers are reported. Intrinsically stretchable optical waveguides capable of >100% strain are formed by coating a commercially available elastic urethane fiber (“Stretch Magic”) with a silicone cladding having a lower refractive index. These 1–2 mm diameter fibers can be attached to textiles using a sewing machine. Because the attaching threads create microbends in the fiber, the sewn fibers are prestrained for monotonic intensity‐versus‐strain behavior. Installed in a stretchable piece of athletic tape, they detect strains originating from changing muscle shapes during weight‐bearing activity.
