A team of researchers at the University of Maryland in the US have unveiled a new, highly sensitive, bolometer made from graphene that can detect infrared light. Although the current version of the device only works at low temperatures, newer models should work at room temperature, says the team. These devices could find applications in a wide range of areas, including security screening at airports, medical imaging and in terahertz radio astronomy.
