some have asked how the new CGM system will be more accurate? Actually, it is in the predictive-corrective software. The more accurate that is, the better the CGM predicts where your Glucose levels are heading, and the insulin basal rate or bolus rate will adjust to the predictive signal received by the pump. That is what was so hard about the development of the artificial pancreas (also called closed-loop controlled pumps.
We will still need to input how much food we will be taking. Seems to me, if it was really smart, it would seek input on carbs, protein and fat, since they all hit at different times after eating. But only the carbs hit so rapidly. The others would be predicted by the software, so maybe proteins and fats aren’t necessary to know.
Dexcom must already have some of this software, because it is a really accurate CGM, and it has enabled me to reduce my A1C from when I relied on the really inaccurate Medtronic CGM (which is not the CGM they will use for the Artificial Pancreas–they will have a new one out).
