Cameras fitted with a new revolutionary sensor will soon be
able to take clear and sharp photos in dim conditions, thanks to a new image
sensor invented at Nanyang Technological University (NTU).
The new sensor made from graphene, is believed to be the
first to be able to detect broad spectrum light, from the visible to
mid-infrared, with high photoresponse or sensitivity. This means it is suitable
for use in all types of cameras, including infrared cameras, traffic speed
cameras, satellite imaging and more.
Not only is the graphene sensor 1,000 times more sensitive
to light than current imaging sensors found in today’s cameras, it also uses 10
times less energy as it operates at lower voltages. When mass produced,
graphene sensors are estimated to cost at least five times cheaper.
