Methods and apparatus for wireless power transfer and communications are provided. In one embodiment, a wireless power transfer system comprises an external transmit resonator configured to transmit wireless power, an implantable receive resonator configured to receive the transmitted wireless power from the transmit resonator, and communications antenna in the implantable receive resonator configured to send communication information to the transmit resonator. The communications antenna can include a plurality of gaps positioned between adjacent conductive elements, the gaps being configured to prevent or reduce induction of current in the plurality of conductive elements when the antenna is exposed to a magnetic field.

Antenna designs for communication between a wirelessly powered implant to an external device outside the body

Systems and methods for physical authentication of medical devices during wireless pairing are disclosed herein. The method can include receiving a request to initiate coupling. Following the request, a visual identifier can be generated with a light source. The visual identifier can include embedded data used to couple the medical devices. The visual identifier can be captured in image data, which image data can be analyzed and the embedded data can be extracted from the image data. Based on the embedded data that is extracted from the image data, secure coupling between medical devices can be established.

Methods for physical authentication of medical devices during wireless pairing

Systems and methods for wireless energy transfer are described. A transmitter unit has a transmitter resonator with a coil that is coupled to a power supply to wirelessly transmit power to a receiver unit. A receiver unit has a receiver resonator with a coil coupled to a device load. The receiver unit can include a ferrite enclosure to prevent transmission of magnetic flux into electronics of the receiver unit, and can include ferrite fins to increase a coupling between the transmitter resonator and the receiver resonator.
