Abstract

Methods and systems for automatically detecting an impedance of one or more electrodes in a cochlear implant system include providing an implantable cochlear stimulator coupled to one or more electrodes, generating an electrical stimulation current with the implantable cochlear stimulator in accordance with stimulation parameters, automatically detecting an impedance of at least one of the electrodes in accordance with a predefined schedule, and performing a predefined action in accordance with the detected impedance.
