Wireless Body Area Network for Sleep Staging

This paper reports the development of a Wireless Body Area Network (WBAN) for sleep staging applications. A prototype biopotential sensor node has been designed for monitoring a multitude of biopotential signals. A system consisting of three of these nodes packaged in a headband enables wireless sleep stage monitoring. Preliminary results obtained from a one-night test on a healthy patient suggest that the proposed system is suitable for sleep staging applications. By removing most of the wires, the proposed system improves the patient´s comfort and the quality of the signals during sleep studies. It paves the way towards remote sleep monitoring and telemedicine applications.
