Abstract: Disclosed herein are embodiments of novel WPT systems, devices, and methods of using the same. Also disclosed herein are methods for controlling the power delivered from a stationary source (e.g., a primary coil) to a moving telemetric device (e.g., a secondary coil) via magnetic resonance coupling. The systems, device, and methods described herein can be used to tune and/or detune resonant frequency between a primary coil and a telemetric device so as to prevent device malfunction and/or tissue damage for the small animals associated with the telemetric device.

Abstract: Disclosed herein are embodiments of a novel WPT system to deliver power from a stationary source (e.g., a primary coil) to a moving telemetric device (e.g., a secondary coil) via magnetic resonance coupling. Novel configurations of the secondary employing ferrite components placed at specific locations and orientations within the coil. Embodiments of these secondary coil configurations are constructed and their performance is tested. Measurements show that ferrite components improved power transfer at most orientations, beyond that of the nominal ferrite-less configuration. The use of angled ferrite components further improved power transfer.
