New communications and radar systems require small and tunable high-frequency devices, since their backbone is the Internet-of- Things (IoT). The need for ultrafast, low-energy-consumption information processing of an exponentially increasing data volume will lead to a global mobile traffic reaching 4394 EB by 2030, thus starting the 6G era (data rate up to 1 Tb/s) of an “ubiquitous virtual existence”. In today’s wireless applications, radar sensors play one of the major roles. Due to the increased need for higher sensitivity and non-destructive inspection systems, the frequency of the radar sensors has reached up to 300GHz on silicon-based technologies. On the other side, 60GHz radar sensing is considered one of the main products for smart home, non-destructive material classification, monitoring vital signals, and all the IoT application that need micro-motion detection. The market penetration for these sensors is now hampered by (i) the limited antenna performance (mainly for the 300GHz case) and (ii) the frequency selectivity and tunability (mainly for the 60GHz case). SMARTWAY proposes novel architectures based on new paradigms that exhibit a significant decrease in energy consumption while improving on speed/performance and miniaturization. The disruptive nature of the targeted approach relies on a progress towards the wafer-scale integration of two-dimensional (2D) materials, metamaterials (MMs), and carbon nanotubes (CNTs) into radar sensor suitable for IoT sensing applications at both millimetre-waves (i.e., 24–60GHz) and THz frequencies (i.e., 240–300GHz). The final outcomes of the project will be two demonstrators, apt to provide industry compatible solutions for radar sensor technologies. For the first time, the nanotechnological paradigms “2D materials” and “CNTs” will be harmonized with the MM concept, thus producing brand-new designs of large-scale complete systems with emphasis on compatibility and integration of different materials/technologies.
