Researchers at the University of Michigan have devised a way to capture the infrared spectrum, which can be made so thin that it can be easily applied on night vision contact lenses.
The first room-temperature light detector that can sense the full infrared spectrum has the potential to put heat vision technology into a contact lens.
“We can make the entire design super-thin,” said Zhaohui Zhong, an assistant professor of electrical engineering and computer science. “It can be stacked on a contact lens or integrated with a cell phone.”
A team at the University of Michigan's College of Engineering led by Zhong and Ted Norris have recently published research in the journal Nature Nanotechnology.
To make the device, they put an insulating barrier layer between two graphene sheets. The bottom layer had a current running through it. When light hit the top layer, it freed electrons, creating positively charged holes. Then, the electrons used a quantum mechanical trick to slip through the barrier and into the bottom layer of graphene.
The positively-charged holes, left behind in the top layer, produced an electric field that affected the flow of electricity through the bottom layer. By measuring the change in current, the team could deduce the brightness of the light hitting the graphene.
“The challenge for the current generation of graphene-based detectors is that their sensitivity is typically very poor. It’s a hundred to a thousand times lower than what a commercial device would require,” said Zhong.
The device is already smaller than a pinky nail and is easily scaled down. Zhong thinks arrays of them as infrared cameras.
“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.”
