Sub-GHz UWB biomedical communication

Abstract

This paper proposes the use of sub-GHz impulse radio Ultra-Wideband (UWB) communication for implantable medical devices. This new concept can offer a more reliable, safer and lower power consuming wireless link compared to other biomedical communications today. An operating frequency below 1 GHz is required to minimize the dielectric absorption of the human tissue and simultaneously allows for low power electronics. Investigating the antenna-electronics interface show that a current driven antenna results in the most reliable signal transfer. This interface is not bounded to the conventional 50 Ω interface.
