2D Materials Push Paper Electronics Towards the Internet of Things

Paper-based electronics have primarily been limited to use in printed organic electronics. While this is promising for commodity applications such as packaging tags and toys, the speed of organic semiconductors is not suitable for most radio-frequency applications. Among the uses for which paper-based electronic devices have been heretofore unsuitable is connecting to the cloud over Bluetooth frequencies for the Internet of Things (IoT), smart sensors, and other smart applications.

Researchers at the University of Texas at Austin (UT-Austin) are reporting this week at the International Electron Devices Meeting that graphene and molybdenum disulfide (MoS2), with their extraordinary conductivity, can enable paper-based electronics to achieve the frequency required to make them fit for IoT and smart sensor applications. The researchers claim that this work represents the first time that high-performance two-dimensional (2D) transistors have been demonstrated on a paper substrate.
