Flexible graphene detector extends scope of terahertz sensors

Researchers at Chalmers University of Technology in Sweden have developed a first-of-its-kind flexible detector for terahertz frequencies using graphene transistors on plastic substrates. Flexible detector for Terahertz sensor Terahertz radiation can be used in everything from airport security and medical imaging to wireless communication. However, the difficulty of applying terahertz detectors to low-cost, flexible substrates has so far limited the technology to larger, more expensive applications such as security scanners. The detector, which is presented in a paper in the journal Applied Physics Letters , could extend the use of terahertz technology to applications such as wearable electronics and […]
