A low-power multi-modal body sensor network with application to epileptic seizure monitoring. 
Monitoring patients' physiological signals during their daily activities in the home environment is one of the challenge of the health care.  New ultra-low-power wireless technologies could help to achieve this goal.  In this paper we present a low-power, multi-modal, wearable sensor platform for the simultaneous recording of activity and physiological data.  First we provide a description of the wearable sensor platform, and its characteristics with respect to power consumption.  Second we present the preliminary results of the comparison between our sensors and a reference system, on healthy subjects, to test the reliability of the detected physiological (electrocardiogram and respiration) and electromyography signals.
