The team of engineers and computer scientists placed an insulating layer between two graphene layers and then added electric current. When infrared light hits the layered product, its electrical reaction is amplified strongly enough to be converted into a visible image.
“If we integrate it with a contact lens or other wearable electronics, it expands your vision,” said Zhong. “It provides you another way of interacting with your environment.”
Night vision contacts are still years away — the research needs to produce greater light sensitivity, as well as the ability to work in a broader range of temperatures.
