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.
Claims9
An ophthalmic device comprising:
- a three-dimensional feature having a cylindrical shape;
- electrical contacts formed upon the three-dimensional surface;
- an electronic element attached to the electrical contacts, wherein the electronic element comprises a thinned flexible semiconductor bent to conform to the three-dimensional feature along at least a portion of the cylindrical shape.
