Graphene contact lenses will help you gain infrared vision
James bond has always been a lot of different spy gadgets and gadgets. And he obviously would not hurt contact lenses with infrared vision. Such a thing may soon become a reality thanks to engineers at the University of Michigan and a wonder material – graphene.
We know a lot about the capabilities of graphene and it can do amazing things. In particular, this material can easily absorb light energy and emit many electrons. But unfortunately, graphene is very thin material and not able to absorb a lot of light. Therefore, the researchers decided to use two layers of graphene with an insulator between them. When the light hits the top graphene layer, the electrons pass through the dielectric to the bottom layer. This process almost a hundred times increases the number of electrons, giving the phototransistor sensitivity, comparable with a digital camera.
But how all this will help in creating contact lenses? The fact that graphene is sensitive to multiple wavelengths of light. Including outside the visible spectrum. Currently, the prototype, created by scientists from Michigan are sensitive to normal light and infrared rays. And because of its thickness technology is ideal for creating contact lenses. Besides the obvious use in espionage, these lenses can be used in other industries, such as medicine.
