The development of low-cost, efficient, printable RFID sensors is a fundamental research domain for Internet of Things (IoT). Chipless RFIDs are a new and emerging technology that removes the silicon chip from the sensor tag, including both the identification and the sensing function in the tag design.
A chipless sensor is basically made by one or more RF resonant structures, whose frequency is dependent on the dielectric material covering the metallic resonator.
This PhD position is about the study of chipless RFID technology for the sensing of ionizing radiation. The study will have different combined approaches:
-At material level: study and identify the best polymer formulation for maximising the sensitivity to different types of radiation (x-rays, ?-rays)
-At device level: build a sensor prototype with the most promising covering material, for both high-dose and low-dose irradiation.
Evaluate its performances, with radiation test and RF measurements, establishing also the suitability for wireless detection.
The work will be in collaboration between DII-Unitn and FBK, with irradiation tests performed at TIFPA or in other Italian INFN labs
