What Is EDA? How Smart Rings Use Electrodermal Activity for Health Monitoring
Introduction As wearable health technology continues to evolve, smart rings are becoming an important platform for continuous physiological monitoring. Beyond traditional measurements such as heart rate, blood oxygen saturation (SpO₂), sleep, and heart rate variability (HRV), a growing area of interest is electrodermal activity (EDA). EDA provides valuable information about changes in the electrical…
