High doses wireless radiation sensor using electromagnetic transducers

This communication reports the last results obtained on the development of a wireless passive chipless sensor for high doses radiation monitoring. The sensor is based on polymer out-gazing inside a micro-chamber coupled with electromagnetic pressure transducer. Previous results on test structures have validated the principle of polymer out-gazing under nuclear radiation. An hermetic sealed prototype including the micro-chamber and the pressure transducer is reported here for the first time. This sensor has been fabricated successfully. Experimental results are reported and discussed.
