(a,b) FE-SEM images of synthesized Cu NWs on PDMS substrate with different magnifications. (c) Specular transmittance at a wavelength of 550 nm as a function of sheet resistance of the Cu NW electrodes. (d) Durability test of the Cu NW-based electrode under the strain of 30%. (e) Resistance change of Cu NW-based electrode at 1000th cycle under the strain of 30%. (f) Durability test of the Cu NW-based electrode under the strain of 100%, the inset graph shows the resistance change from 145 to 150th cycle (R0 = 10 \(\Omega \)). (g) Relative resistance changes under various strains of 10 and 90 \(\Omega \backslash \mathrm{sq}\) electrode.
