In situ electrical wiring with the CNT fiber. (a) Demonstration of CNT fiber device capability with in situ electrical connection between two separated Au electrodes on the mica substrate using the CNT fibers (with diameters of (i) ~500 nm, (ii) 1 μm and (iii) 5 μm) pulled by the proposed NF fabrication procedure. (b) Corresponding mechanical properties. The measured shear modulus is ~1.5 GPa, which is ~4 times higher than the Au nanoparticle-delivered NF case. (c) High electrical property. The measured current density is about 2 orders higher than that of Au nanoparticle NF.
