Abstract
An object is to provide a cochlear implant system (also known as an artificial inner ear system) which is easy to use with little interference with daily activities. A cochlear implant device (or artificial inner ear device) includes an inner ear electrode, an information processing circuit, a transmitter/receiver circuit, a charging circuit, and a battery; and the battery is charged with electromagnetic waves received by the transmitter/receiver circuit through the charging circuit. In addition, the power stored in the battery is supplied to the cochlear implant device. Further, the electromagnetic waves received by the transmitter/receiver circuit are converted into a signal by the information processing circuit, and the signal is provided from the inner ear electrode to stimulate the auditory nerve.
