Wearable Photoplethysmographic Sensor Based on Different LED Light Intensities

Wearable photoplethysmographic sensors in the form of wristbands and watches have become increasingly popular in mobile healthcare. We propose a technique to cancel motion artifacts by using two reflective pulse signals from a single green LED, switched by a microcontroller between high and low ligh...
