Cardiovascular disease is a major cause of death worldwide. New diagnostic tools are
needed to provide early detection and intervention to reduce mortality and increase both the …

The following paper investigates published work on non-contact human physiological
parameter measurement, more precisely measurement of the human heart rate (HR) and …

We present a simple, low-cost method for measuring multiple physiological parameters
using a basic webcam. By applying independent component analysis on the color channels …

Terahertz wave radar offers a higher resolution and smaller aperture compared with
microwave radar. However, despite the emergence of terahertz sources and detectors …

This paper introduces heart sound detection by radar systems, which enables touch-free
and continuous monitoring of heart sounds. The proposed measurement principle entails …

The measurement of physiological parameters is fundamental to assess the health status of
an individual. The contactless monitoring of vital signs may provide benefits in various fields …

Physiological signs can be remotely observed from the physiological and physical effects
caused by a cardiorespiratory activity. A wide range of research on remote cardiorespiratory …

Heart rate variability (HRV) is a useful clinical tool for autonomic function assessment and
cardiovascular diseases diagnosis. It is traditionally calculated from a dedicated medical …

This review provides an overview of unobtrusive monitoring techniques that could be used
to monitor some of the human vital signs (ie, heart activity, breathing activity, temperature …

In recent years, cardiovascular diseases are on the rise, and they entail enormous health
burdens on global economies. Cardiac vibrations yield a wide and rich spectrum of essential …
