Implementation of a telemetric-monitoring system in a cochlear implant

Presents a telemetric-monitoring system which is incorporated in a cochlear implant. This system allows (1) the measurement of voltages at active channels determining the electrode impedances, (2) the measurement of voltages at passive channels for the estimation of the field distribution along the electrode array, and (3) the measurement of the implant supply voltage within a voltage range of 0.1 V>
