pulse camera

A pulse camera, often called a photoplethysmography (PPG) camera, is a device that detects blood flow and heart rate by capturing subtle changes in skin color or brightness caused by blood pulsing under the skin. It uses a regular camera or a specialized sensor to record these tiny variations, which can reveal vital signs like heart rate, rhythm, and blood circulation non-invasively. Pulse cameras are useful in health monitoring, fitness tracking, and medical diagnostics, providing real-time data without needing physical contact or invasive procedures.
