Abstract
An apparatus, system, and method for multicoil telemetry are disclosed. In one embodiment, the apparatus includes an intermediate coil disposed between a driving coil and a receiving coil, where the intermediate coil is configured to act on magnetic fields between the driving coil and receiving coil in order to provide improved coupling efficiency. The improved coupling may assist in providing efficient power transfer and/or data transfer utilizing the magnetic fields. In some embodiments the receiving coil may be in direct communication with the intermediate coil, without any other intermediate coils. In some embodiments, the apparatus includes a second intermediate coil disposed between the driving coil and receiving coil to improve the transfer efficiency between the driving and receiving coils. The intermediate coils may have a high quality factor and be configured to decouple the resistance between the driving and receiving coils.
