New Camera Sensor Eliminates Need for Flash


Virtually no flash? No problem. A new imaging sensor could soon allow photographers to take very clear, sharp photos, even around dim lighting.

Created using a team of researchers during Nan yang Technological University (NTU) around Singapore, the new sensor is definitely highly sensitive to either visible and infrared lumination, which means it may just be used in everything with the family Nikon to security and satellite cameras.

A sensor, which is 1, 000 times more sensitive to light versus the imaging sensors of a lot of today’s cameras, gets the following high photoresponse from it has the innovative structure.
It’s produced from graphene, a super strong carbon compound which includes a honeycomb structure that is often as flexible as rubber, more conductive than silicon plus which resists heat as good as a diamond.

Graphene, which is a one atom-thick layer of your mineral graphite, has already earned a reputation as being the building material into the future. Andre Geim and Konstantin Novoselov had home the Nobel Prize in physics 2010 for their work together with the compound.

The inventor of your new sensor, Wang Qijie, a strong assistant professor at NTU’s Education of Electrical and Digital camera Engineering, said this is at the first try that a broad-spectrum, high photosensitive sensor is made using pure graphene.

“We have shown that must be now possible to make cheap, sensitive and flexile devices from graphene alone, inches said Wang. “We expect our innovation has great impact not only to the consumer imaging industry, and in satellite imaging plus communication industries, as well as being the mid-infrared applications. ”

Wang said the major to his new sensor is the utilization of “light-trapping” nano structures that use graphene for a base. The nano structures hold onto light-generated electron particles for weeks than conventional sensors.

This translates into a stronger than standard electric signal, which is often processed into an photo, like a photograph captured using a digital camera.

Most of today’s camera sensors employ a complementary metal-oxide semiconductor for a base. But Wang said this his graphene base is significantly more effective, producing clearer, crisper photos.

And, according so that you can Wang, he even took current manufacturing practices into consideration when designing this innovative sensor. In principle, the camera industry will keep using the same process in making its sensors, but simply replace the base materials to get graphene.

If the industry chooses to embrace his design, Wang said it could lead to cheaper, lighter cameras with longer battery lives for anyone.
