Development of a measurement error model of new factory-calibrated continuous glucose monitoring sensors used in type 1 diabetes therapy

After an overview of the T1D therapy, the techniques to measure the glucose concentration and a description of Dexcom G6 sensor are illustrated. Then, the issue of CGM sensors inaccuracy and the principal sources of error are presented. A complete description of the available data and of the data pre-processing is provided. Two-step and the single-step identification methods are proposed. The parameters are identified and results are analyzed.
