Claim 28:
29. A cochlear implant system comprising:
a cochlear electrode comprising a first contact electrode;
a stimulator in electrical communication with the cochlear electrode, the stimulator comprising a first source element in electrical communication with the first contact electrode;
a return electrode; and
one or more controllers configured to:
(a) apply an initial compliance voltage to the first source element;
(b) cause the stimulator to emit a first predetermined electrical current from the first source element to the return electrode via a first current path;
(c) determine a first voltage corresponding to a voltage at the first contact electrode relative to a reference voltage;
(d) determine a second voltage corresponding to a voltage at the return electrode relative to the reference voltage;
(e) determine a first impedance associated with the first current path based on the determined first voltage, the determined second voltage, and the first predetermined electrical current emitted from the first source element; and
(f) determine one or more stimulation parameters for the first source element based on the determined first impedance.
