Abstract
Devices, systems, and techniques for managing heat generated in coils for wireless energy transmission are disclosed. Inductive coupling between two coils may be used to recharge the power source of an implantable medical device. A phase change material may be thermally coupled to a flexible coil to absorb heat generated during the inductive coupling and reduce temperature increases of the flexible coil. The flexible coil may be configured to at least one of transmit energy to or receive energy from a second coil, and the phase change material may be configured to deform with the flexible coil and absorb heat from the flexible coil. The phase change material may be contained within thermally conductive tubes or channels configured in shapes that promote flexibility of the flexible coil.
