Abstract
Methods to form a device whereon flexible component elements are attached upon three-dimensional surfaces are described. In some aspects, the present invention includes incorporating flexible semiconductor devices onto three-dimensional surfaces with electrical contacts. In some aspects, the formed device may be incorporated in an ophthalmic device.
Claims7
An ophthalmic device comprising:
- an optical device component;
- a substrate insert having at least a surface region that is non-planar and forms at least a portion of a cylindrical shape contoured around at least a portion of a radial path of the optical device component;
- electrical contacts formed upon the surface region;
- at least a first electronic element attached to the electrical contacts, wherein the first electronic element comprises a thinned flexible semiconductor bent to conform to the surface region along the portion of the cylindrical shape.
