Breakthrough Sensor Could Finally Bring Blood Glucose Monitoring To Apple Watch

Wearable makers like Apple, Samsung, Garmin, and Google have long chased what might be the holy grail of health tech: non-invasive glucose monitoring. Recent developments suggest that Apple could be closer than ever to turning its decade-long ambition into a reality for the Apple Watch.

Blood sugar tracking has been long expected to be the next big thing in wearable health metrics, yet it's remained elusive due to the challenge of measuring glucose without needles. However, change is happening. Current breakthroughs involve two parallel paths: deep integration with existing medical hardware and revolutionary sensor research deep within Apple's skunkworks.

Beginning with the former, Dexcom's G7 continuous glucose monitor can bypass the iPhone entirely, beaming data directly to the Apple Watch. This allows users to monitor their levels during activities like swimming or hiking where a phone isn't practical, representing a transition for the Watch from a ...
