Unobtrusive Body Movement Monitoring during Sleep using Infrared Motion Detector and ZigBee驴 Protocol

摘要

This study was designed to assess body movement during sleep at night unobtrusively using an infrared motion detector and ZigBee communication module. In order to validate the accuracy of this system, motion records and actigraphic data were obtained simultaneously from three young healthy people for three or more consecutive nights. Significant agreement between two data was found by statistical analysis. This body movement monitoring system can assess sleep behaviors on bed without any intervention. Zigbee驴 protocol has an advantage of low power consumption and is suitable for this application.
