Apple looks to be making progress in its long-running ambition to add blood glucose monitoring to the Apple Watch. According to Bloomberg, the company’s no-prick monitoring is now at the “proof-of-concept stage,” and it’s good enough to go to market once it’s smaller. The technology, which utilises lasers to detect glucose concentrations under the skin, was formerly tabletop-sized but has apparently improved to the point where an iPhone-sized wearable prototype is being developed.
