Abstract

This paper reports on experimental trials with an Under Mattress Bed Sensor (UMBS), an easily deployable, non-contact, low cost alternative to the actigraphy watch for sleep monitoring. Results from a home-based study of elderly subjects confirm accurate temporal resolution of activity monitoring in bed. UMBS activity classification thresholds were determined by maximizing Matthew's Correlation Coefficient between the activity data captured using an actigraphy watch and the proposed sensor. Preliminary results on a healthy young subject showed very high agreement rates justifying its use as a replacement for wrist actigraphy.

摘要

本文报道了一项关于床垫下睡眠传感器（UMBS）的实验性试验，该传感器是一种易于部署、非接触式、低成本的设备，可替代用于睡眠监测的活动记录仪手表。一项针对老年受试者的家庭研究结果证实，该传感器能准确监测床上活动的时间分辨率。UMBS的活动分类阈值是通过最大化活动记录仪手表采集的活动数据与该传感器采集的数据之间的马修斯相关系数来确定的。对一名健康年轻受试者的初步结果显示，两者的一致性非常高，证明它可替代手腕活动记录仪。
