Apple's long-running quest to bring blood glucose monitoring to the Apple Watch appears to be moving forward. Bloombergsources claim the company's no-prick monitoring is now at a "proof-of-concept stage" and good enough that it could come to market once it's smaller. The technology, which uses lasers to gauge glucose concentration under the skin, was previously tabletop sized but has reportedly advanced to the point where an iPhone-sized wearable prototype is in the works.
The system would not only help people with diabetes monitor their conditions, but would ideally alert people who are prediabetic, the insiders say. They could then make changes that prevent Type 2 (adult onset) diabetes.
