For its newest smart watch, the ScanWatch, Withings pieced together two health monitoring technologies: one that detects the heart condition atrial fibrillation, and one that measures blood oxygen levels during sleep.
The ScanWatch sends light through the blood vessels in the wrist to measure the amount of oxygen in the blood. Monitoring oxygen levels could help detect episodes of low oxygen that occur with sleep apnea, a condition where breathing stops during sleep, Withings CEO Mathieu Letombe said in a press release. Blood oxygen readings are also integrated with other data around sleep, like sleep duration and quality.
It seems to be a similar feature to one FitBit includes in its Ionic smartwatch. Neither FitBit nor ScanWatch…tech, The Verge, The Verge - All Posts
