Abstract
The measurement of heartbeat rate and breathing rate for patients with sensitive skin, such as skin with burns, is very difficult to do, especially if the number of patients is large and medical personnel is limited. Therefore, this study seeks to propose a preliminary solution to this problem by proposing a device that can measure the vital signs of several people concurrently, especially the heartbeat rate and breathing rate, without attaching sensors to their skin. This is done using an FMCW (frequency-modulated continuous wave) radar that operates at 77–81 GHz. FMCW radar emits electromagnetic waves towards the chest of several targets and picks up the reflected waves. Then, using signal processing of these reflected waves, each target’s heartbeat rate and breathing rate can be obtained. Our experiment managed to perform concurrent detection for four targets. The experimental results are between 52 and 82 beats per minute for the heartbeat rates and between 10 and 35 breaths per minute for the breathing rates of four targets. These results are in accordance with normal heartbeat rate and normal breathing rate; thus, our research succeeded in proposing a preliminary solution to this problem.
Highlights
This paper reports the research results on the detection of human vital signs using a frequency-modulated continuous-wave (FMCW) radar with a concurrent detection approach
Its power density is lower than the Maximum Permissible Exposure (MPE) recommended by the Institute of Electrical and Electronics Engineers (IEEE) [26]
The motivation of this research was to identify effective strategies for dealing with the measurement of heartbeat rate and breathing rate for patients with sensitive skin, such as skin with burns, especially if the number of patients is large and medical personnel is limited. Our experiment solved this problem by measuring the vital signs of four targets at once using an FMCW radar with a frequency of 77–81 GHz as a remote sensor
Summary
This paper reports the research results on the detection of human vital signs using a frequency-modulated continuous-wave (FMCW) radar with a concurrent detection approach. Briefly called vital signs, show the state of the important functions of the human body. There are several known vital signs [1]. The main ones are heartbeat rate, breathing rate, body temperature, and blood pressure. If a person’s vital signs are different from the normal values, it is an early sign that this person is experiencing a health problem [2]. Only heartbeat rate and breathing rates are discussed. In this paper, if we mention vital signs, we mean heartbeat rate and breathing rate
