  • Passive sensor for measuring ionizing radiation
    Patent number: 11156729
    Abstract: The present invention is a passive sensor to detect ionizing radiation over time. It employs a SAW sensor that incorporates a polymer film that deforms based on the chain-scission reaction as described upon irradiation. The polymer film coats the piezoelectric substrate and reflectors on the SAW sensor and, as it reacts to radiation, the film deforms due to the fracturing of the polymer molecules resulting in a loss of overall mass. As the SAW sensor is interrogated by an electrical signal, the wavelength of the response will change as the overall rigidity of the polymer film changes allowing for the detection of the level of radiation.
