Clicking pictures without flash, at a dark shadowy place seems a problem for everyone. But now its not a big deal. The new imaging sensor could soon make it possible for the photographers to take clear and sharp photos in dim light.
A team at NTU in Singapore, has created a new light sensor. The sensor is 1000 times more sensitive to light than the presently used sensors in cameras. Because of this property, it receives a high response (or more likely, Photoresponse) from the structure.
Material Used
How ?
The nano structures of graphene would work as 'light tapping nano structures'. These nano structures hold onto light generated electron particles for much longer than conventional sensors.This results in a stronger electric signal which can be processed into an image as if the photo is clicked from a digital camera.
The graphene based cameras would produce far more better and sharp images than present cameras - claimed by the scientists. Moreover it would lead to cheaper and lighter cameras for all.
The night or dark room photography would at be at a boom through such a technology.

Material Used
- The sensor is made of Graphene.
- Graphene is a super strong carbon compound with a honeycomb structure.
- It is nearly one atom thick layer of the mineral graphite.
- It is as flexible as a rubber.
- It is more conductive than silicon and, resists heat in a better way as a diamond does.
