Abstract:: Abstract: A mobile system for monitoring human physiological parameters is designed based on Android mobile phone. Based on the characteristics of electrocardiogram signals and pulse wave signals, a hardware acquisition system is designed. Using the Bluetooth wireless communication method, the physiological signals collected by the hardware circuit are sent to mobile phone. Through the APP developed on Android mobile phone, the digital filter processing, real-time display, storage and echo display of electrocardiogram signals and pulse wave signals are realized. A continuous blood pressure calculation model is established based on measured pulse wave transit time, and then is verified and tested with the measured blood pressure. Finally, the APP of the established system is run on multiple brands of Android mobile phones to verify the practicality and compatibility of the system. With the advantages of small size, low cost and real-time continuous monitoring, the mobile system realizes the continuous monitoring of the physiological parameters.
