摘要： Systems, devices, and methods for improving wireless power transmission are disclosed herein. A method of powering an implantable ventricular assist device with an external charging device includes receiving a signal indicative of a change in a property of a deformable coil of the resonant circuit. A performance property of the deformable coil is determined based on the signal. An adjustment to a tuning of the resonant circuit is identified based on the performance property of the deformable coil. The resonant circuit is tuned according to the adjustment to the tuning of the resonant circuit. The resonant circuit is driven to transmit power to a secondary coil electrically coupled with the implantable ventricular assist device to power the ventricular assist device.
