a Relative resistance change of the Ni-Ti interconnect as a function of applied strain, showing a negligible hysteresis behavior when loading and unloading. b Relative resistance change under cyclic stretching from ε = 0% to ε = 100% with a frequency of 0.025 Hz over 1000 cycles, the inset shows a zoomed-in image of relative resistance change between cycle 90 and 110. c Stretchable LED array device fabrication flow chart. d Optical image of the LED array device under stretching, the scale bar is 10 mm. Pink paper was used as the background to make the interconnects clear.
