A highly stretchable CuNW electrode was fabricated on PDMS substrate by the vacuum filtration method. The fundamental stretchability of CuNW films was demonstrated with a newly structured PDMS matrix. Our novel helix-structured CuNW/PDMS electrode showed excellent stretchability at an extremely high strain of 700%, showing a resistance variation of 3.9.
