Abstract
An approach that can be used for exploiting the sensing capabilities of radio-frequency identification (RFID) is presented and formulated. In this approach, sensor information is carried through the modulation frequency of RFID . The aim of this work is to investigate the sensor concept and to characterize the sensor performance both theoretically and experimentally. Furthermore, the operation of the sensor radio-frequency (RF) parts and oscillator are described analytically, and the equationsare verified by simulations and measurements. The concept is experimentally demonstrated at a single carrier frequency to test its suitability for ultra-high frequency (UHF) RFID applications, and shown to be feasible for implementing sensors that can be read across distances up to 14 meters.
