(a) Photographs of a light-emitting device under various strain values. (b) Snapshot of the light-emitting device under different deformations. (c) Luminance changes with the strain applied up to 100%. (d) Luminance of Cu NW-based electrode EL device compared to ITO-based electrode EL device. (e) Luminance changes of the EL device placed in room temperature, ambient conditions for 7 days. (f) The resistance changes of Cu NW electrode exposed directly in the air and Cu NW electrode stacked in the EL device for 7 days.
