Demonstration of a Passive Wireless Radiation Detector Using Fully-Depleted Fully Silicon-on-Insulator Insulator Variable Capacitors
s Abstract: Passive wireless sensing of Co Co-60 gamma radiation using fully-depleted depleted silicon-onsilicon insulator (FDSOI) variable capacitors is demonstrated. A linear relationship between resonant frequency and radiation dose is observed for water-equivalent water doses up to 100 Gy, with a frequency change per unit dose of -2.02 2.02 kHz/Gy. These results show FDSOI technology has the potential to realize u ultra ltra-small passive wireless radiation dosimeters with high sensitivity for a wide range of medical and security applications.
