Contact lens with integrated inorganic semiconductor devices

Conventional contact lenses are simple polymer structures primarily used for the correction of vision. In this paper, we present a set of microfabrication techniques that allow for integration of various micro-devices onto a contact lens. The integration of function into the structure of a contact lens opens a number of intriguing venues such as incorporation of a semi-transparent display directly on the structure of a contact lens or the inclusion of a bio-sensor directly on the surface of the cornea. We also discuss methods used to render the lens biocompatible for use in a rabbit eye.
