SLED vs. LED in Wearable Sensors: Which is the Future of Biometric Tracking?

The wearable technology market has undergone a radical transformation over the last decade. We have moved from simple 3-axis accelerometers that counted steps to sophisticated wrist-worn laboratories capable of tracking heart rate variability (HRV), blood oxygen (SpO2), and even performing electrocardiograms (ECG). However, as we move toward the “Holy Grail” of wearables—non-invasive glucose monitoring and […]
