Photoplethysmography (PPG) is a simple optical technique used to detect volumetric changes in peripheral blood circulation. It’s used in smart watches, for example, to monitor pulse and heart rate, but PPG biosensors are also found in millions of smartphones, but without any current clinical applications.
In a study published…
