#$%^&*AU2019246841B220191128.pdf#####ABSTRACT There is disclosed a wireless power transfer system, comprising: an external transmitter configured to transmit wireless power by manipulating evanescent fields outside of tissue to generate propagating fields inside the tissue and thereby generate a spatially focused field inside the tissue； and an implantable device configured to receive the wireless power from the external transmitter, the implantable device including at least one sensor or stimulator configured to sense a parameter of the tissue or apply stimulation to the tissue. Also disclosed is a method for wirelessly powering an implanted device using a mid-field coupler device, the method comprising: exciting at least one coupling structure in the mid-field coupler device using an excitation signal； transmitting a wireless power signal from the at least one excited coupling structure, the transmitting including manipulating evanescent fields outside of a patient's body and thereby generating electromagnetic waves propagating inside the patient's body； receiving, at the implanted device, at least a portion of the wireless power signal transmitted by the mid-field coupler device； and in response to receiving the portion of the wireless power signal, at least one of: applying an electrostimulation therapy to the patient using the implanted device, and sensing a patient parameter using a sensor coupled to the implanted device.WO 2015/039108 PCT/US2O1-4/055885 11/14 ZA) AN L.L a.4) CDC LL
