Abstract

We have previously shown that 25nm thick gold stripes on 1mm thick silicone membrane retain electrical conduction when stretched up to 100% along their long dimension. To function as electrical interconnects in conformable integrated circuits, the metallization must be stretchable in arbitrary directions. Therefore we have made and tested the mechanical and electrical properties of complex conductor patterns including X and Y oriented lines and cross junctions. We find that the metal patterns continue to conduct under uniaxial stretching in the X or Y direction and under radial, biaxial stretching.
