1. A system for measuring the impedance at the electrode-body interface comprising:

  • a processor;

    an alternating current generator in communication with the processor, the alternating current generator having an output voltage and an output impedance; and

    a plurality of electrodes in communication with the processor and the alternating current generator, each electrode having an electrode-body impedance,wherein the processor calculates the impedance at the electrode-body interface in response to the output impedance of the alternating current generator, the output voltage of the alternating current generator and the voltage between two or more of the electrodes.
