基于压电薄膜传感器的睡眠监测枕研究
资料介绍
针对人体睡眠的健康监测问题,分析睡眠时人体头部对枕头压力状态变化,研究出一种基于聚偏氟乙烯(PVDF)压电薄膜传感器的睡眠监测枕。睡眠时采集人体脉搏、呼吸及鼾声生理信号,硬件电路调理、MSP430F149单片机有机处理后经蓝牙上传至LabVIEW程序,结合打鼾无规则振动特征,依据信号幅值、均值同预设值对比的双阈值分析方法,实现睡眠时呼吸暂停识别报警,鼾声自动监测记录及睡眠呼吸暂停综合症前期检查监测等功能。
Aiming at the health monitoring problem of human sleep,the pressure changes of human head on the pillow during sleeping was analyzed,and a sleeping monitor pillow based on PVDF piezoelectric film sensors was developed in this paper.The physiological signals of human pulse,breathing and snoring were collected during sleeping,after organically processing by the hardware circuit conditioning and MSP430F149 microcontroller;the physiological signals were uploaded to the LabVIEW program by Bluetooth.Combined with the irregular vibration characteristics of snoring,according to the double threshold analysis method of signal amplitude,mean and preset value,the apnea recognition alarm,sleep snoring automatic monitoring and sleep apnea syndrome p...
