提出了一种基于压力传感器阵列的人体睡眠呼吸和姿势监测系统。该系统由221个压力传感器(力敏电阻：FSR)安装在床面上。压力传感器阵列的每个传感器间隔5[cm]。该系统的新特点在于对人体呼吸和姿势的非侵入性和不受限制的监测。非侵入性监测消除了监测针头或导管侵入人体的需要，因此传感器不会给他或她带来疼痛等生理负担。在不受限制的监控中，传感器和它们的电线不会限制他或她的行动自由度。因此，不受约束的感觉不会对他或她施加限制所造成的心理负担。实验结果表明，该系统对人体6小时以上的呼吸和姿势监测是可行的。
This paper proposes a monitoring system for a human respiration and posture in sleep using pressure sensor array. The proposed system consists of 221 pressure sensors (Force Sensing Resistors: FSRs) attached to the surface of the bed. Each sensor of the pressure sensor array is set 5[cm] apart. The novel features of the proposed system lie in non-invasive and unrestrained monitoring of the human respiration and posture. Non-invasive monitoring eliminates the need for monitoring needles or catheters to invade the human body, sensors thus do not impose a physiological burden such as pain on him or her. In unrestrained monitoring, sensors and their electrical cords do not limit degrees of freedom of his or her movement. Unrestrained sensing therefore does not impose a psychological burden caused by the limitations on him or her. Experimental results demonstrate that the proposed system is feasible for monitoring a human respiration and posture for over 6 hours.
