Fig. 1: Freestanding LM-AgNW thin-film conductor (FS-GaIn).

a Schematic illustration of the FS-GaIn fabrication process (i) SEM of the FS-GaIn. (ii, iii) SEM of the LM-AgNW thin-film after and before laser exposure, respectively. b The FS-GaIn held by tweezers. c Conformal contact of the FS-GaIn with a human ear model and a rigid component. d The tree-patterned FS-GaIn. e In situ circuit reconnection with a FS-GaIn repair patch and stretchability after reconnection. (i) A disconnected circuit with LED off. (ii) The reconnected circuit by the FS-GaIn repair patch with LED on. (iii) Stable operation of the repaired circuit under stretched condition with the well-operating LED and the repair patch. Scale bars: 200 μm (a-i), 6 μm (a-ii, iii), 2 mm (b), 10 mm (c), 4 mm (c inset), 3 mm (d, e).
