Biocompatibility of implantable antennas: Design and performance considerations

Biocompatibility is one of the most important aspects that need to be taken into account when it comes to implantable antennas. However, very few studies have addressed the effects that biocompatibility considerations might have on the design and performance of implantable antennas. This study addresses the conversion of non-biocompatible implantable antennas into their biocompatible equivalents, exploring the difficulties and proposing solutions. Two methods are suggested for ensuring the biocompatibility of implantable antennas, and these are further investigated and compared. The proposed biocompatible antennas are finally evaluated within an anatomical head model for intra-cranial pressure (ICP) monitoring applications.
