Background Photoplethysmography is a noninvasive and low-cost method to remotely and
continuously track vital signs. The Oura Ring is a compact photoplethysmography-based …

Wearable devices, such as smart watch use photoplethysmography (PPG) signals for
estimating heart rate (HR). The motion artifacts (MA) contained in these PPG signals lead to …

The photoplethysmographic (PPG) signal has the potential to aid in the acquisition and
analysis of heart rate variability (HRV) signal: a non-invasive quantitative marker of the …

In this study, correlation of heart rate variability (HRV) results in different postures between
ECG-based and PPG-based cardiac measurement devices is explored. Electrocardiogram …

Photoplethysmography imaging (PPGI) sensors have attracted a significant amount of
attention as they enable the remote monitoring of heart rates (HRs) and thus do not require …

We present VitaMon, a mobile sensing system that can measure the inter-heartbeat interval
(IBI) from the facial video captured by a commodity smartphone's front camera. The …

The potential of imaging photoplethysmography for cardiovascular monitoring applications
has been demonstrated recently. Various processing schemes have been proposed to …

Cardiac monitoring based on wearable photoplethysmography (PPG) is widespread
because of its usability and low cost. Unfortunately, PPG is negatively affected by various …

Accurate estimation of heart rate (HR) using reflectance-type photoplethysmographic (PPG)
signals during intensive physical exercise is challenging because of very low signal-to-noise …

Photoplethysmography (PPG) is an easy and convenient method by which to measure heart
rate (HR). However, PPG signals that optically measure volumetric changes in blood are not …
