Near-Field Inductive-Coupling Link to Power a Three-Dimensional Millimeter-Size Antenna for Brain Implantable Medical Devices.

Objective: Near-field inductive-coupling link can establish a reliable power source to a batteryless implantable medical device based on Faraday's law of induction.

Methods: In this paper, the design, modeling, and experimental verification of an inductive-coupling link between an off-body loop antenna and a 0.9  three-dimensional (3-D) bowtie brain implantable antenna is presented.
