This year’s Apple Watch upgrade will reportedly add another potentially transformative medical feature: a blood sugar sensor.

That’s according to a new report from ET News, which says both Apple and Samsung will bake the feature into their respective smartwatches — the Apple Watch Series 7 and Samsung Galaxy Watch 4 — later in 2021.

CES 2021 bug A new device shown off at CES may look like an Apple Watch knockoff, but its maker says it can do something Cupertino’s wearable can’t: accurately and noninvasively measure a person’s blood sugar level.

Japanese manufacturer Quantum Operation says its prototype employs a miniature spectrometer to scan blood in the wrist for biomarkers that reveal glucose levels. The user supposedly just puts on the smartwatch and activates the monitoring with a touch. After 20 seconds, the wearer receives the blood sugar data on the device’s screen.
