As prominent components of the Internet-of-Things (IoT) front-end, sensors capable of intelligently collecting sensing information from the surrounding environment with increasingly lower prices are required. Planar microwave chipless sensors could be a valid solution and will be the focus of this PhD research proposal. With a completely passive solution, that in its basic configuration is composed by only microstrip resonant structures and sensitive materials, this frequency-domain sensing technology results particularly adapt for the integration in smart devices. The objectives of the PhD activity will be to contribute with a further investigation of sensitive materials in the context of environmental monitoring and to test their reliability as sensitive components in controlled wired condition. The purpose is, then, to move from a wired controlled measurement to a wireless reading acquisition of the microwave sensing node response. Finally, the sensor potentialities will be further enriched by adopting fabrication techniques typical of the flexible electronics field. An inkjet printing strategy is investigated for the purpose trying to ensure good detection properties as in the case of standard fabricated tags. |
