Body Area Network: Connecting and powering things together around the human body

Abstract

A body area network (BAN) provides connectivity and power among on-body/in-body sensors and is an attractive means for realizing the 'human intranet' for health-care, medical, or multimedia applications around the human body [1], [2]. As shown in Figure 1, compared to a WLAN or a wireless personal area network (WPAN), it targets a much smaller range (∼2 m) with greater energy efficiency.
