Fabrication of conducting fibres with UPy-MWCNT/Ag nanobelt hybrid materials. (a) Photograph of fibre spinning using spinning nozzle and turn table. (b,c) FESEM image of (b) CNT-Ag nanobelt/PU composite fibre and (c) its surface. (d) Lighting of LED lamp through connection with a stitched conducting fibre. (e) Change in resistance of conducting fibre containing 15 wt.% UPy-MWCNT/Ag nanobelt hybrid materials with increasing strain. (f) Strain sensor behaviour of conducting fibre on finger (gauge factor ~60).
