SYSTEMS AND METHODS FOR MEASURING ELECTRODE IMPEDANCE DURING A NORMAL OPERATION OF A COCHLEAR IMPLANT SYSTEM

摘要

An exemplary sound processor may include a stimulation management facility that 1) receives an audio signal presented to the patient during a normal operation of the cochlear implant system, and 2) directs a cochlear implant of the cochlear implant system to generate and apply an electrical stimulation pulse representative of the audio signal by way of an electrode included in a plurality of electrodes coupled to the cochlear implant. The sound processor may further include an impedance management facility that determines an impedance of the electrode by directing the cochlear implant to measure a voltage level associated with the electrode while the electrical stimulation pulse is being applied by way of the electrode. Corresponding systems and methods are also described.

1. A sound processor included in a cochlear implant system associated with a patient, the sound processor comprising:
a stimulation management facility that
receives an audio signal presented to the patient during a normal operation of the cochlear implant system, anddirects a cochlear implant of the cochlear implant system to generate and apply an electrical stimulation pulse representative of the audio signal by way of an electrode included in a plurality of electrodes coupled to the cochlear implant; and an impedance management facility that determines an impedance of the electrode by directing the cochlear implant to measure a voltage level associated with the electrode while the electrical stimulation pulse is being applied by way of the electrode.
