Wave Propagation with Human Body Communications in BANs

Today's interest in health assistance systems, sport activities, person's vital signs observing and remote patient monitoring require distributing various types of sensors at specific places across the human body. These sensors might be used to measure temperature, blood pressure level and the like. This implies collecting the data generated at the distributed sensors in a wireless Body Area Network (BAN) and fusing these data at a central processing unit (e.g. wristwatch), which transfers the data, if needed, to a hospital or medical center for diagnosing. However, sending data wirelessly is typically a very energy intensive task implying large batteries. Hence, BAN networks have been developed by IEEE 802.15. Task Group (TG6) to serve a variety of applications including medical, consumer lifestyle and entertainment applications at low power consumption.
