Abstract

RFID tags can operate in a wide variety of environments enabling battery-free pervasive sensing. In this paper, time-varying impedance measurements are presented to evaluate the sensitivity of inductive-matched dipole antennas as ice thawing monitors. Relative Signal Strength (RSS) measurements of an encapsulated RFID tags based on a commercial IC are presented showing that the tags can be read for up to 45 minutes inside 9~mm-thick thawing ice. Furthermore, the relationship between the ice thickness and the RSS of the ice-loaded RFID tags. The experimental results show that inductive-fed dipole antennas are highly suited for RFID-based monitoring of ice formation and thawing for smart city and remote sensing applications.
