A wearable device for collecting multi-signal parameters of newborn

In recent years, wearable health monitoring equipment has developed rapidly, but most functions are relatively single and can only monitor certain physiological parameters of the human body. This paper designed a wearable mull-physiological parameter monitoring system, which can continuously monitor multiple physiological parameters of newborns for a long time without affecting the normal human activities. The hardware circuit uses MSP430F1611 single-chip microcomputer as the central processing unit. The single-chip computer program completes the calculation of multiple parameters and sends them to the Bluetooth module through the serial port. The Bluetooth module receives the data and transmits it through the module antenna. After testing, each function module works normally. The results of the heart rate measurement experiments show that more than 96% of the heart rate data is within +/- 3 BPM (Beat Per Minute). The experimental results of arterial oxygen saturation measurement show that the error of arterial oxygen saturation is within +/- 2%. The results of arterial blood pressure measurement experiments show that the error between systolic and diastolic blood pressure meets the standard.
