Electronic contact lens heralds on-eye displays

摘要

Bionic eyes have come one step closer with the development of an electronic contact lens. US researchers have used microscopic manufacturing techniques to emhed an electronic circuit into a wearable, flexible contact lens. The lens has been tested on rabbits for periods of 20 minutes and appears to be safe, said researchers. As well as a circuit, the lens is also embedded with tiny light-emitting diodes (LEDs). "Looking through a completed lens, you would see what the display is generating, superimposed on the world outside," said Babak Parviz, an assistant professor of electrical engineering at the University of Washington.
