The SenseWear armband as a Sleep Detection DeviceThe SenseWear armband as a Sleep Detection DeviceSunseri, M., Liden, C.B., Farringdon,J., Pelletier, R., Safier, S., Stivoric, J., Teller, A., Vishnubhatla,S. AbstractAmong sleep researcher and clinicians, there is a need for a cost-effective and easy-to-use tool that can obtain objective, accurate and reliable sleep data in a free-living environment to assist in the screening, diagnosis and treatment of sleep disorders. BodyMedia’s SenseWear Armband which addresses this need, utilizes a 2-axis accelerometer, heat flux sensor, a galvanic skin response sensor, skin temperature sensor and near-body ambient temperature sensor to gather data leading to the calculation of various sleep parameters. This paper outlines our studies which demonstrate how the SenseWear Armband differentiates sedentary activities from sleep and has accuracy rates for sleep onset, wake and total sleep that are comparable to some existing sleep detection devices while addressing their limitations. . |
