Remote Photoplethysmography using Commercially Available Webcams

, 2021
Photoplethysmography (PPG) is a non-invasive method used to measure heart rate by utilizing light. On the other hand, Remote photoplethysmography (rPPG) is a cutting-edge technology that enables contactless monitoring of human cardiac activities. It achieves this by detecting the pulse-induced subtle color variations on the human skin surface using a ...

Role of reactive oxygen species in mediating peripheral hypoxic vasodilation and sympathoexcitation at high altitude

The Journal of Physiology, EarlyView.
Abstract figure legend High‐altitude acclimatisation increases muscle sympathetic nerve activity (MSNA) via activation of the arterial chemoreflex, pulmonary arterial baroreceptors and resetting of the sympathetic vascular baroreflex. However attempting to silence these mechanisms only partially normalises MSNA, implicating other contributory ...

Advances in Electrocardiogram‐Based Non‐Invasive Blood Glucose Monitoring Technology

Diabetes, Obesity and Metabolism, Volume 28, Issue 6, Page 4445-4463, June 2026.
ABSTRACT Blood glucose monitoring is fundamental to diabetes management, yet traditional invasive methods are limited by patient discomfort and infection risks. In recent years, electrocardiogram (ECG), a conventional tool for cardiovascular assessment, has gained attention as a prospective method for non‐invasive blood glucose monitoring.

Modeling the pulse signal by wave-shape function and analyzing by synchrosqueezing transform

, 2016
We apply the recently developed adaptive non-harmonic model based on the wave-shape function, as well as the time-frequency analysis tool called synchrosqueezing transform (SST) to model and analyze oscillatory physiological signals.
