What this trial studies
This study explores the feasibility of using remote photoplethysmography (rPPG) technology to measure blood pressure through a smartphone camera. By analyzing subtle changes in skin color associated with blood flow, the study aims to develop a predictive model using artificial neural networks to estimate blood pressure accurately. The research will involve collecting rPPG waveforms and correlating them with blood pressure readings to validate the effectiveness of this contactless monitoring method. The ultimate goal is to create a mobile application that can provide users with reliable blood pressure assessments.
Why it matters
Potential benefit: If successful, this technology could offer a non-invasive, convenient method for individuals to monitor their blood pressure at home.
How similar studies have gone: While the use of rPPG for other vital sign measurements has shown promise, the application for blood pressure assessment is still novel and untested.
