Graphene sensor holds the key to better low-light photos

Researchers at NTU have announced a sensor made from graphene that can detect broad spectrum light. Compared to traditional CMOS or CCD sensors, the graphene model "traps" light-generated electron particles and can hold on to them for a lot longer, as reported byScience Daily.

By being able to hold on to the electric signals for a longer period of time than regular sensors, the graphene unit can produce clearer photos — particularly in low light situations. The research was led by Assistant Professor Wang Qijie who made the sensor from a pure sheet of graphene, known for its high electrical conductivity.

Graphene is a material that is already set to be used in consumer tech applications such as flexible OLED screens and has long been touted as the replacement for indium tin oxide (ITO). Earlier this year, Fujifilm announced that it was working on touchscreens based on silver halide, which is far more flexible than the brittle ITO currently used in many screens.
