With the growing number of mobile devices surrounding a person’s body, there is an increasing need to connect this electronic equipment efficiently into a wireless body-area network. In this article we review the body-coupled communications technology, which we show to be a viable basis for future BANs. In BCC, the human body is used as a signal propagation medium, which provides a key benefit — the communication is centered around the user and limited to his or her close proximity, that is, this technology provides human-centric connectivity. This enables unique applications that are illustrated in this work. Moreover, we outline the fundamental properties of the BCC technology and provide different trade-offs and challenges for modulation and protocol design. This article alsodiscusses the outlook for BCC and suggests anumber of important research topics.
