Recent researches on implantable antennas for biomedical applications

Abstract

With the rapid development of wireless technologies, wireless communication is making inroads into every aspect of human life. Body-centric wireless communications systems (BWCS) are becoming a focal point for future communications. Wireless implantable systems have obtained a lot of attention in biomedical telemetry. Among these, antennas and propagation are the most basic points for BWCS. Unlike the wearable antennas for on-body or off-body communications, implantable antennas for in-body communication have more challenges due to the poor and complex in-body working environment. An implantable antenna is an important component of a whole implantable system. We should consider the requirements such as size, bandwidth, radiation and safety when designing an implantable antenna. Wireless data telemetry and power transfer are the two big concerns for implantable devices. In this talk, recent research topics for implantable antenna design will be presented and discussed. The topics include circularly polarized implantable antennas design, integrated on-chip antenna for a neuro-system and implantable rectenna design for far-field wireless power transfer.
