Photoplethysmography (PPG) is a simple and low-cost optical technique that can be used to
detect blood volume changes in the microvascular bed of tissue. It is often used non …

The photoplethysmogram (PPG) signal is widely measured by clinical and consumer
devices, and it is emerging as a potential tool for assessing vascular age. The shape and …

Recent studies demonstrated that blood pressure (BP) can be estimated using pulse transit
time (PTT). For PTT calculation, photoplethysmogram (PPG) is usually used to detect a time …

Most traditional cardiovascular risk factors alter the structure and/or function of arteries. An
assessment of arterial wall integrity could therefore allow accurate prediction of …

An optical proximity sensor assembly includes an optical proximity sensor with an IR LED
emitting light having an infrared wavelength, an IR photo detector sensitive to the infrared …

Introduction: We compared the effects of eccentrically-biased (EB) and conventional (CONV)
resistance training on: muscle architecture, 1 repetition maximum (1RM), isometric strength …

The development and validation of a system for multi-site photoplethysmography (PPG) and
electrocardiography (ECG) is presented. The system could acquire signals from 8 PPG …

Arterial stiffness (AS) serves as a crucial indicator of arterial elasticity and function, typically
requiring expensive equipment for detection. Given the strong correlation between AS and …

Distortions in macro-and microcirculation are principal contributors to diabetes-associated
complications. This study aimed at investigating the validity of applying non-invasive …

Increased arterial stiffness is an important marker for target organ damage in essential
hypertension. Both serum uric acid (UA) and C-reactive protein (CRP) were reported to be …
