A team of scientists at Nanyang Technological University (NTU) in Singapore developed a new image sensor made of graphene that improved the quality of images captured in low light conditions.
Based on Science Daily, the new sensor made from graphene is believed to be the first sensor able to detect a broad spectrum of light – from the visible to mid-infrared, with high photoresponse or sensitivity – which mean it is suitable for use in all types of cameras, including infrared cameras, traffic speed cameras, satellite imaging etc.
It has also proven that graphene is 1,000 times more sensitive to light than traditional complementary metal-oxide-semiconductor (CMOS) or charge-coupled device (CCD) camera sensors. In addition, graphene sensors operate at a much lower voltages levels and consumes 10 times less energy. When graphene sensors are mass produced, they believe that it will reduce the cost by at least five times.
The inventor of the graphene sensor, Assistant Professor Wang Qijie, from NTU’s School of Electrical & Electronic Engineering, said:
While designing this sensor, we have kept current manufacturing practices in mind. This means the industry can in principle continue producing camera sensors using the CMOS (complementary metal-oxide-semiconductor) process, which is the prevailing technology used by the majority of factories in the electronics industry. Therefore manufacturers can easily replace the current base material of photo sensors with our new nano-structured graphene material.”
Low voltage, low energy and cheap, with this I believe that graphene will lead us to buy cheaper cameras with a longer lasting battery life in the future. And graphene still has many undiscovered potential – it only gets better!
