Abstract
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 b…
