Abstract

Nowadays, daily vital sign monitoring can effectively prevent chronic diseases and has a very important position in the field of medical research. However, the monitoring method is basically contact-based, which causes inconvenience to the daily life of users. This work presents a set of integrated real-time monitoring device system for respiration, pulse, and blood pressure based on the characteristics of non-contact and wide range of milli-meter wave radar. The device obtains data by monitoring the wrist of the human body in a relaxed state. Through image processing and machine learning, the respiration and pulse waveforms with good accuracy are separated, and the obtained blood pressure value also has a certain accuracy. The milli-meter wave radar itself has the advantages of low power, simple circuit, and good integration, so the device has a great market prospect.
