Apple Watch Series 7 may bring blood glucose monitor, patent describes the tech

What’s more is that the tech could mean faster battery drain than before and if the timepiece can fit-in all the components.

Apple might just bring a new health-focussed technology in its Watch coming later this year. The new Watch, tipped Apple Watch Series 7, may be able to monitor blood glucose without drawing blood. And a new patent now shows how that tech might be implemented. The patent application filed with the US Patent and Trademark Office (USPTO) titled “Terahertz Spectrosopy and Imaging In Dynamic Environments With Performance Enhancements using Ambient Sensors” states that the iPhone maker can use absorption spectroscopy to obtain non-invasive blood sugar readings.

Also mentioned is that the tech could use terahertz electromagnetic radiation instead of using light to pass through the body to detect "gas, health/quality of liquid or solid materials." But the patent also mentions a potential issue. The implementation of the tech could result in the Watch losing water resistance. The blood sugar reading has to be accurate as well. If the reading is off by a bit, the user may end up taking too much insulin and bring on a hypoglycemic or low blood sugar attack, reports Phonearena.

What's more is that the tech could mean faster battery drain than before and if the timepiece can fit-in all the components. In all of this would mean an increase in the price of the device.

The report adds that the same tech can be used to detect skin cancer and other related problems. However, although the patent doesn't necessarily mean that Apple will definitely bring blood glucose monitors to Apple Watch, it does mean that the company is at least considering working on it. For what's worth, Samsung is also expected to bring a blood glucose monitor in its next smartwatch that is expected to arrive later this year.
