a Change in the normalized resistance with increasing strain on Cu/PDMS and EGaIn/Cu/PDMS. b, d SEM images and energy-dispersive X-ray spectroscopy (EDS) analysis before (top) and after (bottom) strain (50 ~ 70%) is loaded to (b) Cu/PDMS and (d) EGaIn/Cu/PDMS. c, e An LED connected with (c) Cu/PDMS and (e) EGaIn/Cu/PDMS before (top) and after (bottom) stretching (~30% strain). The scale bars in (b) and (d) are 50 μm.
