Graphene is a thin, flexible and strong material with lots of applications in different fields. Adding to it’s many uses, researchers at MIT have now found a way to create graphene based Night Vision Lenses that are thin and powerful at the same time.
These lenses use graphene-based thermal sensor, which cover the full infrared spectrum for easy detection. In addition to the graphene, there is also a silicon microelectromechanical system (MEMS) integrated to the design.
This system helps in cutting out the heat interference in the system, which occurs while trying to recognize heat patterns from long distances.
The face that this can be done without the need for cryogenic cooling is what makes these lenses so small, yet so efficient.
Just by using the system and the sensor, the majority of the bulk is cut off from the night vision apparatus.
This change lets night vision be installed in smaller frames, like Contact Lenses. This small form factor could prove very useful for soldiers as well as rescue workers, who need to be very careful with the weight of their equipment.
Another relevant application would be for self driving cars, who could use this sort of superior night vision technology to enhance their night time driving.
It is expected that with time, more applications of this technology would make themselves known. But for now, it’s just a concept with the potential to change how we perceive darkness.
If you want to know more about how the process works, you can find the details in the researchers’ paper for this technology, which has been published in the American Chemical Society (ACS) journal Nano Letters.
