Superhero Vision With Graphene Contact Lenses?
Graphene, a 2-dimensional crystalline allotrope of carbon, is capable of detecting the entire infrared spectrum with visible and ultraviolet light therefore it could be used to enhance human vision although there have been technical limitations such as the fact that it can absorb only 2.3 percent of the light that hits it. This problem seems to be solved now by researchers at the University of Michigan.
To achieve this amplification, the researchers started by sandwiching an insulator between two sheets of graphene. The bottom sheet has an electrical current running through it. When light hits the top sheet, electrons are freed and positively charged electron holes are generated. The electrons are able to perform a quantum tunneling effect through the insulator layer, which would be impenetrable in classical physics.
“If we integrate it with a contact lens or other wearable electronics, it expands your vision,” Zhong said in the release. “It provides you another way of interacting with your environment.”
I’ve told you in my recent white paper, The Guide to the Future of Medicine, we would soon experience the rise of “recreational cyborgs” with augmented human capabilities just because they can afford it.
