Soon, night vision contact lenses

Researchers have developed a new sensor that could lead to night vision contact lenses.

Electrical Engineers, Ted Norris and Zhaohui Zhong, at the University of Michigan discovered a method to sense infrared light using two layers of an atom-thick layer of carbon, known as graphene, the Verge reported.

Instead of relying directly on the graphene's sensitivity to light, Norris and Zhong measured an electrical current running alongside the graphene layer.

Their findings revealed that as light hits the top graphene layer, it leaves a measurable impact on the flow of electricity below it and produces an electrical signal which could display a night vision image.

Zhong said integrated with a contact lens or other wearable electronics, it expands your vision.

The findings have been published in journal Nature Nanotechnology.
