“Over the past few months, Apple has hired a formidable team of biomedical experts with deep experience in medical sensor technologies. Notably, many of the folks now working for Apple have done impressive and groundbreaking work in the realm of continuous glucose monitoring (CGM),” Heisler writes. “Many news outlets, as a result, have reported that Apple’s rumored iWatch may be able to non-invasively measure a user’s glucose levels.
