Focus Session on “Additive manufacturing based RF sensors and RFIDs for rugged IoT and Digital Twins in smart cities”
In the context of digital twin in smart-cities, there is a need of future system-level solutions for ultra-low-cost Millimeter-Wave Modules for 5G+ Communication, Energy Harvesting and Sensing applications. In this effort, an inkjet-printed 60GHz backscatter 5G RFID modules is proposed. This work is a stride forward towards the realization of large-scale deployment of RFID modules for sensing and localization applications. Then a 3D printed high density Chipless RFID tag, based on a spectral encoding scheme is described. The information is concealed inside the inner structure of the tag, to prevent unwanted reading process. The third study presents A low-cost passive vibration transducer for massive structural monitoring by means of Chipless RFID Sensor Tags. The displacement transducer is based on a 3D directional coupler, with coupled-line sensitive to vibrations. The last study focuses on the detection of VOCs. The sensors are based on inkjet-printed planar microwave transducers. The gas detection is obtained from a differential approach between two channels with and without the sensitive nanomaterial PEDOT: PSS-MWCNTs.
Workshop on “Materials by Design for Microwave and mm-Wave Communications”
Innovations in material science are crucial for the ongoing development of faster, high-throughput wireless communications at microwave and mm-wave frequencies. As communications systems advance into the mm-wave regime, low-loss materials are needed for fast, efficient, on-chip signal transmission. High-mobility materials are required for energy-efficient transducers that enable small-cell-based platforms. New measurement methods and material testbeds are needed to understand nonlinearity and intermodulation. Tunable materials are required for beam-forming applications and other reconfigurable systems. Materials-by-design approaches to advanced materials offer the enticing possibility of engineering optimal property-performance material relationships to meet these needs. Materials-by-design approaches can be applied across a wide variety of relevant systems, including ferrite ceramics, tunable oxides, perovskites, and novel nanomaterials. In the context of developing devices for wireless communications, materials-by-design can serve as the foundation of a multifaceted approach that includes materials engineering, materials and device modeling, measurements, and ultimate incorporation of material building blocks into microwave and mm-wave systems.
