Compliant and stretchable three-dimensional golden tracks are produced by metallization of silicone wires maintained under twisting and stretching constraints. Upon release, the metallic track deforms to a helix presenting a wavy and cracked surface. Wavelet and crack orientations are function of three parameters: the wire radius, the number of imposed rotations divided by the length of the cylinder, and the stretching in its axis direction. Electrical conductivity at rest and under stretching can be optimized by finding the prestraining conditions that provide the best trade off between the maximum amount of surface buckling and a limited amount of cracks.
