Bionic Contact Lens

Bionic contact lenses are being developed to provide a virtual display that could have a variety of uses from assisting the visually impaired to the video game industry. The lenses require organic materials that are biologically safe and also use inorganic material for the electronic circuits. The electronic circuits are built from a layer of metal a few nanometres thick. The light-emitting diodes are one third of a millimetre across. A grey powder is sprinkled onto the lens. Then a technique called microfabrication or ‘self-assembly’ is used to shape each tiny component. Capillary forces pull the pieces into their final position.

Wireless communication, radio frequency power transmission and solar cells are expected in future developments. The prototype does not light up or display information; however, it is proof that it is possible to create a biologically safe electronic lens that does not obstruct a person’s view. Engineers have tested the finished lenses on rabbits.
