Claim 0:
1. A method of determining contact status of electrodes, the method comprising:
applying drive signals between pairs of electrodes;
measuring a bipolar electrode complex impedance (BECI) value generated in response to the drive signals over a collection period;
determining a baseline BECI value representing a minimum value measured during the collection period; and
determining contact status by:
applying drive signals between pairs of electrodes over a given interval;
measuring a BECI value generated in response to the drive signals;
measuring a peak-to-peak value associated with the BECI values measured over the given interval; and
determining contact status based on a combination of the baseline BECI value, the measured BECI value, and the peak-to-peak value associated with the measured BECI values.
