The present invention relates to stretchable interconnects which can be made in various geometric configurations, depending on the intended application. The stretchable interconnects can be formed of an electrically conducting film or an
elastomer material to provide elastic properties in which the interconnects can be reversibly stretched in order to stretch and relax the
elastomer material to its original configuration. Alternatively, stretchable interconnects can be formed of an electrically conducting film or a plastic material to provide stretching of the material to a stretched position and retaining the stretched configuration. The stretchable interconnect can be formed of a flat 2-dimensional conductive film covering an elastomeric or plastic substrate. When this structure is stretched in one or two dimensions, it retains
electrical conduction in both dimensions. Alternatively, the stretchable and / or elastic interconnects can be formed of a film or stripe that is formed on an elastomeric or plastic substrate such that it is buckled randomly, or organized in
waves with long-range periodicity. The buckling or
waves can be induced by various techniques, including: release of built-in stress of the conductive film or conductive stripe; pre-stretching the substrate prior to the fabrication of the conductive film or conductive stripe; and patterning of the surface of the substrate prior to the fabrication of the
metal film. The stretchable interconnect can be formed of a plurality of conductive films or conductive stripes embedded between a plurality of
layers of a substrate formed of an
elastomer or plastic.
