A Physiological Photoplethysmography Simulator
Photoplethysmography has gained traction recently as a method for non-invasive, cuffless blood pressure monitoring. This technology is subject to interpatient variability and requires calibration based on patient physiology. We propose a simulator fixture mimicking human tissue and blood flow that allows wearable tech companies to manipulate different physiological parameters and optimize their photoplethysmography devices.
