Wireless Body Area Network for Sleep Staging

Abstract

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.
