Fig. 3: Stretchability and mechanical durability of BiLMP-coated fibers.

a Initial electrical conductivity comparison of CaLMP, PaLMP, and BiLMP. b, Relative resistance of conductive fibers under strain with respect to the type of coated film (CaLMP, PaLMP, and BiLMP). c Relative resistance of BiLMP-coated fibers under 10,000 strain cycles. d Peel test of each film with commercialized scotch tape. There is no notable peel-off and residue with CaLMP and BaLMP films. e Resistance variation of BiLMP-coated fibers under repeated attachment and detachment of tape. f Electrical current passing through an attached LED and the resistance of the connected BiLMP-coated fiber interconnect under strain. g Photograph of a sewn electrical circuit with a BiLMP-coated fiber. Scale bar: 2 cm. h Image of large-area integration of BiLMP-coated fibers on commercial cloth. i Image of BiLMP fiber-integrated smart clothes.
