Devices and methods described herein facilitate rapid wireless recharging, while reducing risk of injury, damage, or discomfort caused by heat generated during recharging. The embodiments described herein are useful in a variety of context, including for IoT devices, personal electronics, electric vehicles, and medical devices, among others.

Estimating and controlling skin temperature with low temperature thermal conductivity recharger

Systems and methods for improved user experience with rechargers for implantable medical devices. An external charging device for providing power to a rechargeable implantable device can determine a firmware state of the external charging device during recharging of the rechargeable implantable device, display a searching indication using a light indicator when the firmware state is determined to be in a searching state, display a charging indication using the light indicator when the firmware state is determined to be a charging state, and display an error indication using the light indicator when the firmware state is determined to be an error state. An optional user device application can provide complementary graphical user interfaces according to the firmware states.

User centered system for recharging implanted neurostimulator

An implantable medical system includes an implantable medical device and a external charger. The implantable medical device includes a rechargeable power source, electronic components coupled to the rechargeable power source to deliver a therapy to or monitor a parameter of a patient, and a recharge system operably coupled to the rechargeable power source including a secondary coil to receive power via an inductive power transfer. The external charger includes a housing forming an internal compartment, recharger electronic components disposed on a printed circuit board assembly in the internal compartment, and a recharge coil assembly disposed within the internal compartment, the recharge coil assembly including a recharge coil to provide power to the secondary coil via the inductive power transfer and a flux guide having a ferrite sheet disposed between the recharge coil and the printed circuit board assembly.
