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 presleep monitoring and other functions during sleep can be realized.
