Abstract
A system detects extravasation or infiltration by segregating active components that drive a passive sensor for economical single use. A receiving antenna of the passive sensor receives a transmitted signal comprising RF electromagnetic power. A first circuit transmits a first portion of the received signal through a body portion. A sensor detects a resultant signal from the body portion. A second circuit combines a reference signal comprising a second portion of the received signal with the resultant signal so as to define an output signal. A transmit antenna transmits the output signal to a receiver.
