COCHLEAR IMPLANT POWER SYSTEM AND METHODOLOGY

摘要

A cochlear implant system has an implantable portion (202) that includes a stimulator module (211) for producing for the auditory system of a user an electrical stimulation signal representative of an acoustic signal. The imp lantable portion further includes a battery (209) for supplying power to the stimulator module (208), a receiver module for receiving an electrical powe r signal across the skin of a user, and a recharge module (213) that uses th e electrical power signal to recharge the battery. The recharge module recha rges the battery at less than the maximum recharge rate.
