Fig. 4: Mechanochromic applications of the CLCE-SC fibres.

a Smart fishing lines fabricated from a single LM-CLCE-SC fibre loaded with three fish toys of 200, 500, and 800 g. b Bundled safety rope composed of seven strands of the HM-CLCE-SC fibres, supporting a 5 kg kettlebell. Sequential cutting of the seven strands to three. c Schematic of a dynamic sensory net interwoven with 9 × 9 strands of the LM-CLCE-SC fibres, tested by vertically dropping a steel ball from a height of 15 cm. d and e Photographs of the side and bottom views of the dynamic sensory net during steel-ball dropping. The enlarged photos in (e) show the colour change from red (R) to orange (O), yellow (Y), green (G), and blue (B) at the centre of the net owing to the force applied by the steel ball. f Photographs of the deformed dynamic sensory net affected by different dropping heights and potential energies. g CIE chromaticity diagram for various applications.
