Patent ID: 8552299

Claim:
A method of making a stretchable and foldable electronic device, said method comprising: providing a multilayer device comprising a substrate layer, a functional layer and one or more neutral mechanical surface adjusting layers, wherein said functional layer is supported by said substrate layer, wherein at least one of said one or more neutral mechanical surface adjusting layers is disposed above said functional layer, wherein at least one of said one or more neutral mechanical surface adjusting layers of said multilayer device has a property that is spatially inhomogeneous relative to a location in said multilayer device, wherein said spatially inhomogeneous property positions a spatially varying neutral mechanical surface coincident with or proximate to said functional layer, and wherein spatial variations in said spatially inhomogeneous property causes said spatially varying neutral mechanical surface to be positioned at different distances from a to surface of the multilayer device in different spatial regions of the multilayer device, relative to said functional layer.
