Fascinating technology brought to notice by http://www.uberveillance.com/ October 26, 2012.
See http://www.uberveillance.com/blog/2012/10/26/wbans-1.html "...Wearable sensors in Wireless Body Area Networks (WBANs) provide health and physical activity monitoring.
Modern communication systems have extended this monitoring remotely. In this survey, various types of wearable sensors discussed, their medical applications like ECG, EEG, blood pressure, detection of blood glucose level, pulse rate, respiration rate and non medical applications like daily exercise monitoring and motion detection of different body parts. Different types of noise removing ﬁlters also discussed at the end that are helpful in to remove noise from ECG signals. Main purpose of this survey is to provide a platform for researchers in wearable sensors for WBANs.

WBANs may well have applications in determining the medium to long term health effects of water and air pollution, reactor spill radiation (like Fukushima) as well as mobile phone and other device radiations levels.
Security monitoring-tracking (WBANs as listening and video devices?) is another possible application which may already be in use by security services with the money and know-how - hence human rights advocates should be concerned.
