It should have internal impedance testing unit to test the skin electrode impedance
Contact impedance was constantly monitored using impedance meter to keep electrode impedance
below 5 k ohms.
She discusses the basic science, including the anatomy of hearing loss, principles of electrical stimulation of the auditory system, parts and functions of a cochlear implant, past and present devices, candidacy, and signal delivery with cochlear implants; nonphysiological objective measures, including electrode impedance
, electrical field potentials, and averaged electrode voltages; and physiological measures: electrically evoked stapedial reflexes, compound action potentials, auditory brainstem response, auditory middle latency response, and auditory cortical potentials.

At the same time, the electrochemically active area is being modified, and this led to the observed fluctuating movement of the resistive and capacitive components of the working electrode impedance
This article discusses an alternative aqueous electrode impedance
spectroscopy experimental geometry.
Electrode position is monitored by electrode impedance
A current flow between a contact and case, or between contacts, of <7 [micro]A with an electrode impedance
of >2000 ohms, would suggest an open or an incomplete circuit.
Absolute electrode impedances
and Inter electrode impedances
of less than 5 KO and less than 2 KO respectively were maintained.
Skin to electrode impedances
at 10 Hz using silver/silver chloride electrodes, with the skin properly prepared, are typically about 5k.
