Minimally-invasive continuous glucose monitoring (CGM) sensors measure in the subcutis a current signal which is converted into interstitial glucose (IG) concentration by a calibration process periodically updated using fingerstick blood glucose (BG) references. Though important in diabetes management, CGM sensors still suffer from accuracy problems. Here, we propose a new on-line calibration method improving accuracy of CGM glucose profiles with respect to manufacturer calibration.

Abstract
Minimally-invasive continuous glucose monitoring (CGM) sensors measure in the subcutis a current signal which is converted into interstitial glucose (IG) concentration by a calibration process periodically updated using fingerstick blood glucose (BG) references. Though important in diabetes management, CGM sensors still suffer from accuracy problems. Here, we propose a new on-line calibration method improving accuracy of CGM glucose profiles with respect to manufacturer calibration.File in questo prodotto:
