Photoplethysmography (PPG) is a non-invasive optical technique widely used in the study and monitoring of the pulsations associated with changes in blood volume in a peripheral vascular bed. Over the last thirty years, there has been a significant increase in the number of published articles on PPG, describing both basic and applied research. Throughout these publications the PPG has been hailed as a non-invasive, low cost, and simple optical measurement technique applied at the surface of the skin to measure a whole host of physiological parameters.
The popularity of this topic can be attributed to the realization that PPG has important implications for a wide range of applications, including amongst many, blood oxygen detection, cardiovascular system assessment, and vital signs monitoring. In addition, the recent significant contributions of PPG to wearable devices have had a major impact on the popularity and usability of PPG.
There is currently a large body of literature contributing new knowledge on the relation of the PPG pulse morphology, pulse wave analysis and pulse features extraction with the physiological status of peripheral blood vessels, such as vascular ageing and stiffness, blood pressure and compliance, microvascular disease, autonomic function, amongst others. There are also significant efforts in the utilization of the PPG for the detection of heart arrhythmias such as Atrial Fibrillation (AF). Researchers are continuing to strive in combining the PPG sensory capabilities of wearables, such as smartwatches, with Artificial Intelligence (AI) machine learning approaches in delivering ubiquitous health monitoring solutions that go beyond the current available consumer heart rate wearables.
Scientific interest in PPG continues to rapidly grow and hence the motivation and aim of this Research Topic is to bring together the latest cutting edge basic and applied research in the field of Photoplethysmography.
