In embodiments, the present invention may attach at least two isolated electronic components to an elastomeric substrate, and arrange an electrical interconnection between the components in a boustrophedonic pattern interconnecting the two isolated electronic components with the electrical interconnection. The elastomeric substrate may then be stretched such that the components separate relative to one another, where the electrical interconnection maintains substantially identical electrical performance characteristics during stretching, and where the stretching may extend the separation distance between the electrical components to many times that of the unstretched distance.
