Nanyang Technological University (NTU) in Singapore have found a way to increase picture quality of images taken in low light conditions.
The Scientists who are behind this new discovery has proven this to be 1000 times more sensitive than the current camera lenses. Aside from this they have found that is also uses 10 times less energy than the current charge- coupled devices we use now.
How does it work?
Graphene has a hexagonal structure and is only one atom thick. It is very light and is a high conductor of electricity. Asst. Prof Wang of NTU has devised a way to create nanostructures on graphene which "trap" light-generated electron particles for a longer period of time. These traped light-generated electron particles become a stronger elecrtrical signal which can then be transfered into an image. Essentially, the stronger the electric signals generated, the clearer and sharper the photos.
