Detections of pulse and blood pressure employing 5G millimeter wave signal

Abstract

Currently, non-invasive blood pressure monitoring with using a cuff is commonly used. However, this monitoring method is not suitable for some people who cannot wear the cuff and who might feel uncomfortable and troublesome. Non-contact measurement method provides a safer and more comfortable way to measure blood pressure. This paper describes the research on a non-contact pulse and blood pressure monitoring system. The frequencies of millimeter waves used in this experiment are 28GHz and 32GHz, which are the same as 5G millimeter wave signal. In this experiment, the millimeter waves are transmitted and reflected to the body and measure the reception intensity. As the results, we can detect pulse by utilizing millimeter waves, however, the relationship between blood pressure and millimeter waves needs further investigation.
