  • Apple and its suppliers are currently developing components for next-generation sensors in the Apple Watch Series 8. 
  • This will allow users to measure their blood glucose levels.
  • The first Apple Watch was capable of measuring just the heart rate and primary daily activity.
  • The Apple Watch now is capable of taking an ECG, detecting falls, high and low heart rates, blood oxygen levels, and more
  • The Apple Watch Series 7, announced last month, includes a larger display, faster charging, and a slightly larger battery.

Apple and its suppliers are currently developing components for next-generation sensors in the Apple Watch Series 8 that will allow users to measure their blood glucose levels.

According to MacRumors, Apple and its suppliers have begun working on short-wavelength infrared sensors, a commonly used sensor type for health devices. The new sensors, likely to be fitted on the back of the Apple Watch, will enable the device to measure the amount of sugar in a wearer's blood.

The Apple Watch, over the years, has gained more comprehensive health features, most recently with the Apple Watch Series 6 that added a blood oxygen sensor. Compared to the first Apple Watch capable of measuring heart rate and primary daily activity, the Apple Watch is now capable of taking an ECG, detecting falls, high and low heart rates, blood oxygen levels, and more.

Continuing to build the Apple Watch as an all-encompassing health tool, Apple has already been rumoured to be eyeing blood glucose measuring functionality for the next-generation Apple Watch, the Apple Watch Series 8.

However, Apple is facing challenges in incorporating blood glucose capabilities into the Apple Watch. Current methods of measuring blood glucose levels include taking a sample of blood and using a medical-grade device. With the Apple Watch, Apple would be looking to take a typically invasive medical practice and make it non-invasive.

In iOS 15, the Health app added blood glucose highlights as a health metric. iOS 15 users have to use external hardware to provide the data, but that would change if Apple adds a glucose monitoring feature to a future Apple Watch model.

What Apple has in store for the next Apple Watch remains unclear, but the radical redesign that was rumoured for the Series 7 but never materialised could make an appearance. The Apple Watch Series 7, announced last month, includes a larger display, faster charging, and a slightly larger battery. Apple is expected to announce the Apple Watch Series 8 in the 2022 fall season.
