Researchers at Chalmers University of Technology in Sweden have used graphene transistors on plastic substrates to develop a flexible detector for terahertz frequencies.

The team says the first-of-its-kind device can extend the use of terahertz technology to applications that will require flexible electronics, such as wireless sensor networks and wearable technology.

The detector has several unique features: for example, at room temperature, it detects signals in the frequency range of 330 to 500 gigahertz. In addition, it is translucent and flexible, and can be used in a variety of applications.

The researchers say the unique electronic features of graphene, combined with its flexible nature, make it a promising material to integrate into plastic and fabric, something that will be vital in a future connected world run by the Internet of Things.

The researchers' breakthrough is an important step forward for graphene in the terahertz era, and a boon for high-performance and inexpensive flexible terahertz technology.
