Abstract

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