noninvasive glucose sensing

Researchers from the University of California San Diego have developed a low-cost, single-use tattoo-like wearable that measures the user’s glucose levels.

Citing anonymous sources within Apple, reports in Bloomberg and the New York Times over the past weeks continue to add to the pile of leaks and rumors about two of Apple's currently under-development health devices: a wrist-worn glucose sensor and an EKG built into the Apple Watch.

The Apple Watch, announced on-stage at an event in California yesterday, didn't live up to the rumors that it would offer advanced health sensing -- rumors that built up around the "iWatch" thanks to months of reports about Apple's growing team of medical sensor experts.
