Abstract

This paper reviews different kinds of passive wireless sensors utilizing the intermodulation communication principle. The reviewed sensor architectures are based either on a mechanical resonator, electrically non-linear sensing element, or on a separate mixer, low-frequency resonance circuit and a sensing element. The benefits and drawbacks of different architectures are compared and some experimental measurement results are presented.
