Introduction . Monofilament fibers resulting from a thermal draw1 , 2are a unique platform for implementing pervasive, functional devices and systems, from traditional fiber optics for telecommunication through fibers-devices for signal transduction3 , 4 , 5 , 6 , 7 , 8 , 9and energy management10 , 11to fibers with computational and data processing capabilities12 , 13. Fiber fabrication and post-processing combine pulling and shaping the clad...
