Joint Sensing and Communication with Graphene FETs Targeting Terahertz Band

The upcoming 6G paradigm for wireless communication networks promises enhanced data rates, reduced latency, and pervasive connectivity. In this scenario, intelligent and adaptive communication protocols and innovative smart sensing devices can be efficiently integrated to offer innovative systems for different applications. In the future, graphene technology might greatly contribute to the evolving landscape of sensing combined with high-frequency communication. This paper explores possible architectures for radiofrequency (RF) electronics for joint sensing and modulation based on graphene field-effect transistors (GFETs). Current challenges and limitations of graphene technology are also discussed.
