Optical, electrical, and mechanical properties of the hybrid electrode. a Schematic illustration of the silver nanofiber–silver nanowire (AgNF–AgNW) hybrid electrode. b Scanning electron microscope (SEM) of the AgNF–AgNW hybrid electrode. Scale bar, 20 μm. c Transmittance versus sheet resistance of the AgNF–AgNW hybrid electrode. d SEM image of the patterned AgNF–AgNW hybrid electrode. Scale bar is 30 μm. e Dependence of sheet resistance on the pattern widths of the hybrid electrode (pattern length: 500 μm). f Relative resistance changes as a function of the bending radius and bending-induced strain
