Inductive Charging Circuit for Implantable Devices
Implantable devices have seen a large growth in the past years. For humans pacemakers are most common, but more recently other implants like insulin pumps or even cochlear implants have emerged. They all need electrical power that usually is provided from a battery. When only small currents are drawn from the latter then the battery can last long until it needs to be replaced. Wireless charging offers a way to circumvent the exchange for rechargeable batteries.
At the IIS we have developed miniaturized circuits for implantable devices, in particular a power management IC. In this project a extension to it for wireless charging will be investigated. It includes the whole transfer chain as shown in the picture, with the transmit driver, the coils and the charging part on the side of the implant.
