Graphene Image Sensor

Smartphone cameras are excellent, but still lack the optical robustness of a stand alone point and shoot.  But that might soon change thanks to a newly developed camera sensor that is derived from graphene.

Graphene is tiny, which is an understatement.  In fact, according to Sciencedaily it’s a million times smaller than the thickest human hair – that translates to one-atom thick.  So what does this mean in terms of a camera sensor?  Not only is it 1,000 times more sensitive to light than today’s image sensors (CCD and CMOS), it also requires 10 times less energy and is all the while five times cheaper.  Talk about bang for buck.

Invented by assistant professor Wang Qijie, from NTU’s School of Electrical & Electronic Engineering, the new sensor is in a rather nascent stage and will take some time until it starts appearing in actual products.  But since they say it can capture the full spectrum of light, it could appear in anything from satellites to digital point and shoots, and eventually, and hopefully, smartphones.

I can’t help but wonder if it could be used much in the same as the Lytro cameras since it apparently “able to detect broad spectrum light, from the visible to mid-infrared”?
