NEW YORK (TIP): Researchers have developed a cheap imaging camera sensor which is 1,000 times more sensitive to light than those available at present — and could make it possible to click clear and sharp pictures even in dim lighting. The new sensor developed, at Nanyang Technological University in Singapore, is highly sensitive to both visible and infrared light, and could be used in everything, from the family cameras to surveillance and satellite cameras.
The sensor gets the high photoresponse from its innovative structure. It is made of graphene , a superstrong carbon compound with a honeycomb structure that is as flexible as rubber, more conductive than silicon and which resists heat better than a diamond, Tech- NewsDaily reported. The sensor’s “light-trapping” nanostructures hold onto light-generated electron particles for much longer than conventional sensors. This results in a stronger than usual electric signal, which can be processed into clearer, sharper photographs.
