Abstract
Methods of producing a composite substrate and devices made by the methods are disclosed. One of the methods comprises providing a flexible sacrificial layer, producing one or more patterned conducting layers on the flexible sacrificial layer, bending the sacrificial layer into a predetermined shape, providing a stretchable and/or flexible material on top of and in between features of the one or more patterned layers.
