Apple still has a challenge to overcome to market blood glucose monitoring!
He Apple Watch glucose sensor It is one of the most awaited updates for the devices. Even the most optimistic reports predicted its arrival with the launch of the Apple Watch in 2025, but a new report says that’s still a long way off.
Information from Mark Gurman’s “Power On” column indicates that Glucose sensor for Apple Watch, still needs to refine built-in sensors and algorithms to bring technology to market. And according to the trusted analyst, all these changes “will take another three to seven years at least”, contradicting his last posts.
Size matters
This new publication of Gurman contradicts the report shared just a month ago, in which they claimed that Apple was very close to the end goal. materialize a non-invasive blood glucose monitoring technology, ahead of the competition.
At the time, Gurman claimed that Apple was already well ahead of the game by developing a chip technology called “silicon photonics” as well as an “optical absorption spectroscopy” process. It uses lasers that emit wavelengths into an area under the skin where interstitial fluid is present, which can be absorbed by glucose. But while important, it’s only part of the complex process of changing blood glucose sensing.
However, Apple Watch size limitations are one of the biggest barriers to including additional sensors. According to Gurman, Apple is struggling to shrink the sensor down to a size that can comfortably fit inside a smartwatch.
The company’s goal is to provide a tool to notify Apple Watch users if they are prediabetic to encourage lifestyle changes before diabetes develops. He is believed to be leading preliminary discussions on how to gain regulatory approval for the technology.
According to records, Apple has been conducting trials related to a blood glucose sensor for a decade. Bitten Apples began working on this possibility after acquiring RareLight in 2010. The company then used a startup called Avolante Health LLC to develop the technology in a secret facility before handing it over to the Exploratory Design Group (XDG) .
