a Normalized resistance change of EGaIn/Cu/PDMS depending on strain in the range of 0–70%. The maximum strain reached before the PDMS breaks is 70% (Supplementary Fig. 9). The red dots are the theoretical values predicted from Pouillet’s law. b The conductivity stability test of EGaIn/Cu/PDMS during repetitive stretching–releasing cycles. The cycle test utilized 30% strain. The scale bars in inset images are 0.5 cm. L is the initial length of EGaIn/Cu/PDMS before stretching.
