This paper reviews recent advances in biomedical and healthcare applications of Doppler
radar that remotely detects heartbeat and respiration of a human subject. In the last decade …

The seismocardiogram (SCG) is a recording of a human heart's mechanical activity. It
captures fine-grained cardiovascular events such as the opening and closing of heart valves …

As a result of the worldwide transmission of severe acute respiratory syndrome coronavirus
2 (SARS-CoV-2), coronavirus disease 2019 (COVID-19) has evolved into an unprecedented …

Human pulse rate (PR) can be estimated in several ways, including measurement
instruments that directly count the PR through contact-and noncontact-based approaches …

This paper focuses on the exploitation of linear-frequency-modulated continuous-wave
(LFMCW) radars for noncontact range tracking of vital signs, eg, respiration. Such short …

This paper presents the first flip-chip-packaged and fully integrated Doppler micro-radar in
90-nm CMOS for noncontact vital-sign and vibration detection. The use of a smaller …

Using continuous wave, 94-GHz millimeter-wave interferometry, a signal representing chest
wall motion can be obtained that contains both the heart rate and respiration patterns of a …

Current cardiopulmonary activity monitoring is based on contact devices which cannot be
used in extreme cases such as premature infants, burnt victims or rescue operations. In …

A compact millimeter-wave (MMW) sensor has been developed for remote monitoring of
human vital signs (heart and respiration rate). The low-power homodyne transceiver …

The use of radar technology for contactless monitoring of cardiorespiratory activity has been
a significant research topic for the last two decades. However, despite the abundant …
