Apple Watch with blood glucose monitor may arrive next year

Smartwatches today have gained many features that can monitor more than just their activity or movement. They can assess the quality of your sleep, measure your heart rate and, at least in some cases, even take note of your blood oxygen levels. However, there are still some things they cannot do, such as autonomous blood pressure measurement or non-invasive blood sugar monitoring. The latter, however, may be approaching reality with an Apple Watch with such a feature coming in 2022.

Blood pressure monitoring often requires the use of a special cuff or at least some calibration to work. Measuring blood glucose, on the other hand, involves the removal of some fluids from the body, especially a drop of blood. A non-invasive alternative to the latter has been one of the Holy Grails in the medical and technological fields and it is now believed that Apple is on the verge of such an innovative product.

Of course, there is no concrete evidence that this is the case, but a lawsuit at the SEC revealed that, at least, Cupertino is actively working to achieve that goal. British company Rockley Photonics has revealed in documents that Apple is its biggest customer in the United States. It also happens that the company is working on a technology that detects blood sugar levels by means of infrared light.

Apple’s ambitions in this area are no secret, of course, but this is perhaps the first concrete evidence that Apple is preparing to use this technology. The lawsuit reveals that the two companies have a supply and development contract and most of Rockley’s profits came from engineering fees to work on related products.

Perhaps more interestingly, the UK startup’s CEO has revealed that he expects his technology to be in consumer products next year. Of course, he didn’t say whether he would be on the Apple Watch, but some market watchers connecting the dots see it that way.
