Implantable battery device for standard cochlear implant

Abstract

An implantable battery device is disclosed, which comprises a battery, a first antenna, a second antenna, and a driving unit. The first antenna is configured to inductively supply energy from the battery to a first device and to transmit information received from a processing unit to the first device. The second antenna is provided for wireless communication with a second device. The driving unit is configured to operate the first antenna according to control signals received from the processing unit. The processing unit is configured to transmit control signals to the driving unit to control the inductive supply of energy to the first device, to receive information via the second antenna from the second device, and to transmit information received via the second antenna from the second device to the first device via the first antenna driven by the driving unit.
