Abstract

This paper proposes a new coil structure for inductive powering to wearable/implantable biomedical devices. This structure is virtually independent from the direction (and alignment) of the receiving coil relative to the transmitting coil. In addition to conducting experimental tests and characterizations, the proposed coil structure (energized by a transmitting coil) has been used to power up a real test system designed for wireless neural recording, operating at 1.2 V and drawing 48 mW.
