Computational method from embedded wearable PPG for BP/BGL prediction

As cardio-metabolic diseases grow in prevalence, current management and monitoring methods fail to address some of the many inconveniences and difficulties that have existed for a long time. The traditional approaches to blood pressure and blood glucose monitoring are adequately sufficient in produc...
