Removal of motion artifacts is a critical challenge, especially in wearable
electroencephalography (EEG) and photoplethysmography (PPG) devices that are exposed …

Mounting clinical evidence suggests that viral infections can lead to detectable changes in
an individual's normal physiologic and behavioral metrics, including heart and respiration …

In this article, we propose a new on-device photoplethysmography (PPG) signal quality
assessment (SQA) system based on the first-order (FO) predictor coefficient (PC) of …

Due to the high demands of tiny, compact, lightweight, and low-cost photoplethysmogram
(PPG) monitoring devices, these devices are resource-constrained including limited battery …

Photoplethysmography is a method to visualize the variation in blood volume within tissues
with light. The signal obtained has been used for the monitoring of patients, interpretation for …

Photoplethysmography (PPG) is a non-invasive optical method to acquire various vital signs,
including heart rate (HR) and heart rate variability (HRV). The PPG method is highly …

Remote photoplethysmogram (rPPG) is a low-cost method to extract blood volume pulse
(BVP). Some crucial vital signs, such as heart rate (HR) and respiratory rate (RR) etc. can be …

Objective: With the increasing use of wearable healthcare devices for remote patient
monitoring, reliable signal quality assessment (SQA) is required to ensure the high accuracy …

Photoplethysmography (PPG) sensors are widely used to measure a variety of physiological
parameters, from heart rate to clinically important peripheral oxygen saturation (SpO 2). The …

Objective: A patient-independent approach for continuous estimation of vital signs using
robust spectro-temporal features derived from only photoplethysmogram (PPG) signal …
