Report: Apple working on non-invasive glucose testing device – Six Colors

I think there are two "moonshot" projects in the wearable tech space. The first is a way to continuously monitor blood glucose level, the other is to do the same for blood pressure. Both of these metrics change frequently and are very responsive to the things we eat, activities we do, and our environment. If a device like a watch were able to track these things with reasonable frequency it could give very actionable feedback to people on ways to improve their health in the short and long term. It isn't clear that this is even possible to do though, but it is great to see continued research to try.
