Uncertainty and applicability of rfid power measurements for passive sensing

Although RFID sensors are gaining increasing attention from Academic and Industrial world, their true applicability is still in question. The aim of the work is to characterize the RFID sensing platform in term of repeatability and reproducibility, such to answer the question whether and in which condition it is possible to distinguish the variation of the measured signals due to the sensing activity from the measurement uncertainties. The analysis presents theoretical and experimental contributions.
