1. A device for non-invasively determining lung wetness, the device comprising:

  • a sensor comprising a plurality of electrodes, wherein the plurality of electrodes in the active region are configured to form a plurality of pairs of current-injecting electrodes and a plurality of pairs of voltage detection electrodes;

    a signal generator configured to apply a first drive signal comprising a first frequency and a second drive signal comprising a second frequency, wherein the first and second drive signals are applied to a first pair of electrodes of the sensor;

    a processor configured to receive a first recorded signal correlating to the first frequency and a second recorded signal corrected to the second frequency, wherein the first and second recorded signals are received on a second pair of electrodes of the sensor; and

    wherein the processor is further configured to determine lung wetness by operating on the first and second recorded signals independently of the patient'"'"'s body geometry.
