A hydraulic bed sensor has been developed to non-invasively monitor pulse and respiration during sleep. This sensor is designed for in-home use, to be part of an integrated sensor network for the early detection of illness and functional decline in elderly adults. Experience with another bed sensor has motivated a desire to acquire enhanced, quantitative data related to pulse and respiration. This paper describes a working prototype, the signal processing methods used to extract data from the constructed transducer, and results from preliminary testing.
一种液压床传感器已被开发出来，用于在睡眠期间无创监测脉搏和呼吸。该传感器专为家庭使用而设计，是集成传感器网络的一部分，用于早期检测老年人的疾病和功能衰退。对另一种床传感器的使用经验激发了获取与脉搏和呼吸相关的增强型定量数据的愿望。本文描述了一个工作原型、用于从构建的传感器提取数据的信号处理方法以及初步测试的结果。
