A Terminator-style contact-lens display

Bringing us a step closer to a Terminator-style augmented-reality display, University of Washington engineers have constructed an experimental contact lens with a single-pixel embedded light-emitting diode (LED) and tested it in a rabbit.

The LED lights up when it receives energy from a remote radio frequency transmission, picked up by an antenna around the edge and collected via a silicon power harvesting and radio integrated circuit.
