Abstract: Techniques for forming highly stretchable electronic interconnect devices are disclosed herein. In one embodiment, a method of fabricating an electronic interconnect device includes forming a layer of an adhesion material onto a surface of a substrate material capable of elastic and/or plastic deformation. The formed layer of the adhesion material has a plurality of adhesion material portions separated from one another on the surface of the substrate material. The method also includes depositing a layer of an interconnect material onto the formed layer of the adhesion material. The deposited interconnect material has regions that are not bonded or loosely bonded to corresponding regions of the substrate material, such that the interconnect material may be deformed more than the adhesion material attached to the substrate material. In certain embodiments, the interconnect material can also include a plurality of wrinkles on a surface facing away from the substrate material.
