Mechanical properties. a True tensile curves of the intrinsically stretchable conductor at different strain rates. b True tensile curves of the conductor at small strain. c Young’s modulus of the intrinsically stretchable conductor at different strain rates. d Optical micrographs record the autonomously self-healing process of the conductor (scale bar: 100 μm). e True tensile stress–strain curves of the original and self-healing conductor
