Beyond its use in a clinical environment, photoplethysmogram (PPG) is increasingly used for
measuring the physiological state of an individual in daily life. This review aims to examine …

Photoplethysmography (PPG) is a low-cost, noninvasive optical technique that uses change
in light transmission with changes in blood volume within tissue to provide information for …

Photoplethysmography (PPG) technology has been used to develop small, wearable, pulse
rate sensors. These devices, consisting of infrared light-emitting diodes (LEDs) and …

A photoplethysmograph (PPG) is a simple medical device for monitoring blood flow and
transportation of substances in the blood. It consists of a light source and a photodetector for …

Thermal comfort is defined as the condition of mind that expresses satisfaction with the
thermal environment and it is assessed by subjective evaluation. Achieving comfortable …

Blood pressure (BP) is one of the most important monitoring parameters in clinical medicine.
For years, the cuff-based sphygmomanometer and the arterial invasive line have been the …

Measures of heart rate variability (HRV) are widely used to assess autonomic nervous
system (ANS) function. The signal from which they are derived requires accurate …

Heart rate variability (HRV) represents one of the most promising markers of the autonomic
nervous system (ANS) regulation. However, it requires the acquisition of the ECG signal in …

Background Photoplethysmography (PPG) is a low-cost and easy-to-implement method to
measure vital signs, including heart rate (HR) and pulse rate variability (PRV) which widely …

The performance of portable and wearable biosensors is highly influenced by motion
artifact. In this paper, a novel real-time adaptive algorithm is proposed for accurate motion …
