No-Flash Camera

A new imaging sensor, that’s more than a thousand times more sensitive to both visible and infrared light than today’s cameras, makes it possible to take clear, sharp pictures even in dim light without the need for a flash. It’s made of graphene – a one atom thick layer of graphite with a honeycomb structure that’s flexible, highly conductive and heat resistant.

The high photosensitivity is a result of the fact that the nanostructures are capable of trapping light and holding onto the electrons generated for a longer period of time than traditional imaging sensors, which use metal-oxide semiconductors as a base. The stronger than usual electrical signal can then be processed into a clearer, sharper image. And because it eliminates the need for a flash, battery life can be increased.

In addition to the obvious benefits for mobile phone users, the new technology will greatly enhance the efficiency of surveillance and satellite cameras.
