Abstract

Thinned, flexible surface regions upon which flexible active components may be utilized to attach flexible active components in space/volume constrained devices, for example, a powered ophthalmic device. Thinned, flexible surface regions foster an avenue for enhanced functionality because various electronic circuits and components can be integrated into polymeric structures.
