Though its fun to think of the Body Area Network
as another way for cheap employers to get out of paying for properly wiring your workspace, the most obvious uses for this technology would seem to be in the realm of health care. To this end, the National Institute of Information and Communications Technology (NICT
) in Japan has developed an ECG that can be worn 24 hours a day, wirelessly transmitting electrocardiographic data as well as measuring changes in body surface temperature and posture. The data can even be transmitted securely using cryptographic keys dynamically generated by the patient's posture and biological data (which are unique to each user). We'll let you guys ponder the cypherpunk ramifications of this technology in the comments -- and be sure to check out the additional pic we have for you after the break.
