Systems and methods for detecting presence of insulin excipients

The present disclosure provides a glucose sensor, comprising: a working electrode configured to provide a current signal (IsigWE1) based on a glucose level; a background electrode configured to provide a current signal (IsigWE2) based on the presence of the insulin excipient; and a controller. The controller is configured to monitor the IsigWE1 at the working electrode, monitor the IsigWE2 at the background electrode, monitor at least one electrochemical impedance spectroscopy (EIS) parameter at the working electrode, and calculate a change in the at least one EIS parameter, detect the presence of the insulin adjuvant based on the change. In the event that the presence of the insulin excipient is detected, the controller is further configured to compensate for the IsigWE1 based on a predetermined relationship between the IsigWE1 and the IsigWE2, and to output the compensated IsigWE1 (IsigCOMP). 本公开提供了一种葡萄糖传感器，该葡萄糖传感器包括：工作电极，该工作电极被配置为基于葡萄糖水平提供电流信号(IsigWE1)；背景电极，该背景电极被配置为基于胰岛素辅料的存在提供电流信号(IsigWE2)；和控制器。该控制器被配置为监
