摘要：
An apparatus associated with a cochlear implant system used by a patient directs a cochlear implant included within the cochlear implant system and implanted within the patient to generate electrical stimulation current at a predetermined current level. The apparatus further directs the cochlear implant to apply the electrical stimulation current to the patient by way of an electrode coupled with the cochlear implant, and to measure a voltage level associated with the electrode while the electrical stimulation current is applied to the patient by way of the electrode. Based on the predetermined current level and the measured voltage level, the apparatus determines an impedance of the electrode. Based on the determined electrode impedance and in accordance with a predetermined stimulation parameter adjustment constraint, the apparatus automatically adjusts a stimulation parameter associated with the cochlear implant system. Additional apparatuses and corresponding methods are also disclosed.
