Researchers from Nanyang Technological University developed a new camera sensor made from graphene that can detect a broad light spectrum - from visible to mid-infrared - at high sensitivity. The new sensor is 1,000 times more sensitive to light than current imaging sensors, yet it uses 10 times less energy as it operates at low voltages.
The researchers say that they used existing manufacturing practices (a CMOS process) which means that these new sensors can be commercialized rather easily. They now intent to find industry partners to develop this into a real product.
To achieve the high photoresponse the researcher create nanostructurs on graphene that "trap" light-generated electron particels for a long time.
