1. A passive wireless gastroesophageal sensor comprising:

  • a LC resonance circuit;

    two or more electrodes configured to measure an impedance within a gastroesophageal tract; and

    a passive batteryless Radio Frequency Identification (RFID) circuit connected to the LC resonance circuit and the one or more electrodes to transmit a frequency modulated signal using the LC resonance circuit that varies between a first frequency corresponding to a non-acid reflux condition and a second frequency corresponding to an acid reflux condition based on the measured impedance in response to a signal received from a detector.
