Abstract: Chest-acquired photoplethysmogram (PPG) signals often suffer from severe degradation due to motion artifacts and poor perfusion, limiting their clinical utility. We propose a novel style ...

The United States Food and Drug Administration has cleared Apple's new hypertension detection feature, revealed recently for the Apple Watch. Granting clearance on Thursday, September 12, this will ...

A flexible organic photodetector (OPD) has been developed for a flexible organic photoplethysmography sensor (FOPS) designed to monitor vital cardiovascular parameters such as pulse rate, respiratory ...

Abstract: Continuous authentication (CA) based on wrist photoplethysmogram (PPG) has been increasingly studied, but still requires further extensive investigation on PPG reliability over time and ...

Background: During cardiopulmonary resuscitation (CPR), diastolic blood pressure (DBP) is a key driver of coronary perfusion pressure and thereby, blood flow during CPR. Although resuscitation ...

Photopletysmography (PPG) is a non-invasive and well known technology that enables the recording of the digital volume pulse (DVP). Although PPG is largely employed in research, several aspects remain ...

Open clinical trial data provide a valuable opportunity for researchers worldwide to assess new hypotheses, validate published results, and collaborate for scientific advances in medical research.

Fiber-based wearable displays, one of the most desirable requisites of electronic textiles (e-textiles), have emerged as a technology for their capability to revolutionize textile and fashion ...

Noninvasive pulse wave analysis is useful for evaluating vascular load and vascular stiffness. Measurement of arterial function is important to determine the risk for cardiovascular diseases. The ...

The most commonly used method for cuffless blood pressure (BP) measurement is using pulse transit time (PTT), which is based on Moens-Korteweg (M-K) equation underlying the assumption that arterial ...
