Scientists make new sensor that could lead to night vision contact lenses

RATE THIS! +23

Night vision contact lenses may be the stuff of science fiction movies, but new research points the way to how we could some day see in the dark with our own eyes. Electrical Engineers at the University of Michigan have found a new way to sense infrared light using two layers of an atom-thick layer of carbon, known as graphene.

 

Unlike prior methods, the substance doesn't have to be cooled to extremely low temperatures, and the device is very thin and small.

 
The researchers, Ted Norris and Zhaohui Zhong, faced a major hurdle with graphene: it just isn't very sensitive to light. "It’s a hundred to a thousand times lower than what a commercial device would require," said Zhong in a statement. So instead of relying directly on the graphene's sensitivity to light, the scientists decided to measure an electrical current running alongside the graphene layer.
 
Their findings, published last month in Nature Nanotechnology, explain that as light hits the top graphene layer, it leaves a measurable impact on the flow of electricity below it. That produces an electrical signal that can display a night vision image.

Graphene is reaching the stage where many possible applications are getting closer to reality - his night vision is one of them. Very interesting Reply

This will be another way of interacting with our environment. Applications could be many- but this may not be something for mass market

Yes, and recently there was discussion about augmented reality contact lens prototype- embedded in the contact lenses are micro-components that enable the user to focus on near-eye images. Interesting how much we can potentially enhance our vision Reply

I am just wondering what is our brain making of this and how confusing all this could be. Our vision evolved in one way and now we are exposed to all this new things and virtual staff - perhaps all is fine Reply
