How a Simple Model Can Assess PPG Signal Quality on Wearables with 97% Accuracy

Wearables have transformed how we monitor health, but noisy data can compromise their reliability. A groundbreaking study from researchers like Mohammad Feli introduces an energy-efficient, semi-supervised approach for Photoplethysmogram (PPG) Signal Quality Assessment (SQA). Key Results By embedding this lightweight method, wearable devices can deliver more accurate insights while consuming less power—a win for both […]
