Este artigo descreve um sistema de monitoramento de frequência cardíaca sem contato e tolerante a ruído usando um sensor Doppler de micro-ondas de 24 GHz. O sensor Doppler de micro-ondas colocado a alguma distância do peito do usuário detecta as pequenas vibrações da superfície corporal devido aos batimentos cardíacos. O objetivo deste trabalho é detectar a frequência cardíaca instantânea (IHR) utilizando este sistema sem contato em um carro, pois a possível aplicação do sistema proposto é o monitoramento da saúde do motorista baseado na análise da variabilidade da frequência cardíaca. O RSI pode contribuir para a prevenção de desastres desencadeados pelo coração e para detectar estados de estresse mental. No entanto, o sistema do sensor Doppler é muito sensível e pode ser facilmente contaminado por artefatos de movimento e ruído da estrada, especialmente durante a condução. Para resolver este problema, são empregadas análises tempo-frequência usando o método paramétrico e o método de correspondência de modelos. Os resultados da medição mostram que o sensor Doppler, colado na superfície da roupa, pode extrair com sucesso a frequência cardíaca através da roupa. O método proposto atinge um erro RMS de 13.1 ms em medições de RSI realizadas em 11 indivíduos em um carro em uma estrada comum.

Abstract: This paper describes a non-contact and noise-tolerant heart rate monitoring system using a 24-GHz microwave Doppler sensor. The microwave Doppler sensor placed at some distance from the user's chest detects the small vibrations of the body surface due to the heartbeats. The objective of this work is to detect the instantaneous heart rate (IHR) using this non-contact system in a car, because the possible application of the proposed system is a driver health monitoring based on heart rate variability analysis. IHR can contribute to preventing heart-triggered disasters and to detect mental stress state. However, the Doppler sensor system is very sensitive and it can be easily contaminated by motion artifacts and road noise especially while driving. To address this problem, time-frequency analysis using the parametric method and template matching method are employed. Measurement results show that the Doppler sensor, which is pasted on the clothing surface, can successfully extract the heart rate through clothes. The proposed method achieves 13.1-ms RMS error in IHR measurements conducted on 11 subjects in a car on an ordinary road.
