The diabetes market is already being disrupted, by Dexcom, which makes continuous sensors, and which appears to be iterating every few years. You calibrate them every 12 hours or so, they last a week, and they give a sample every 5 minutes or so, at a cost of about $600+$100/week of consumables. The software isn't great, but it gets the job done and it'll download data over an included USB cable and export to CSV if you just want a spreadhsheet.
