The knowledge of heart and respiratory rates (HRs and RRs) is essential in assessing
human body static. This has been associated with many applications, such as survivor …

The vital sign monitoring through Impulse Radio Ultra-Wide Band (IR-UWB) radar provides
continuous assessment of a patient's respiration and heart rates in a non-invasive manner …

A novel non-contact vital-sign sensing algorithm for use in cases of multiple subjects is
proposed. The approach uses a 24 GHz frequency-modulated continuous-wave Doppler …

In this paper, we introduce TR-BREATH, a time-reversal (TR)-based contact-free breathing
monitoring system. It is capable of breathing detection and multiperson breathing rate …

This paper explores using RSS measurements on the links between commercial wireless
devices to locate where a breathing person is located and to estimate their breathing rate, in …

Respiratory rate is an important vital sign that can indicate progression of illness but to also
predict rapid decline in health. For the purpose, non-contact monitoring systems are …

This paper shows experimentally that standard wireless networks which measure received
signal strength (RSS) can be used to reliably detect human breathing and estimate the …

Human respiration state is an important indicator to reflect health conditions. Recent
advances in wireless human sensing have enabled device-free respiration monitoring using …

We developed a noncontact measurement system for monitoring the respiration of multiple
people using millimeter-wave array radar. To separate the radar echoes of multiple people …

Methods, apparatus and systems for detecting and monitoring vital signs in real time are
disclosed. In one example, a system for monitoring a repeating motion in a venue is …
