Photoplethysmography (PPG) is a noninvasive optical technique for detecting microvascular
blood volume changes in tissues. Its ease of use, low cost and convenience make it an …

Camera-based remote photoplethysmography (remote-PPG) technology has shown great
potential for contactless pulse-rate monitoring. However, remote-PPG systems typically …

This study presents the use of a multi-channel opto-electronic sensor (OEPS) to effectively
monitor critical physiological parameters whilst preventing motion artefact as increasingly …

Imaging photoplethysmography is an emerging technique for the extraction of biometric
information from people using video recordings. The focus is on extracting the cardiac heart …

Wearable electronics or epidermal electronics have attracted growing interest for their
expansion into markets as health monitors and for biological applications. However, a key …

In this work, we obtain backscattered signals from human forehead for wavelengths from
380 to 980 nm. The results reveal bands with strong pulsatile signals that carry useful …

Remote photoplethysmography (rPPG) using camera-based imaging has shown excellent
potential recently in vital signs monitoring due to its contactless nature. However, the …

Remote imaging photoplethysmography (iPPG) senses the cardiac pulse in outer skin layers
and is responsive to mean arterial pressure and pulse pressure in critically ill patients …

Photoplethysmography (PPG) is a non-invasive optical technique that can be used to
quantify the arterial blood pulse rate. Signal corruption by motion artifacts limits the practical …

Objective: Blood pressure (BP) data can influence therapeutic decisions for some patients,
while non-invasive devices that continuously monitor BP can provide patients with a more …
