1. A method for monitoring a level of an analyte, the method comprising:
- inserting an electrochemical sensor into skin of a patient, wherein the electrochemical sensor comprises;
a working electrode comprising a sensing layer disposed thereon; and
a reference electrode comprising a layer of Ag/AgCl having a width that is equal to the width of the working electrode and a layer of dielectric material having a width that is at least equal to the width of the layer of Ag/AgCl and a length that is at least equal to the length of the layer of Ag/AgCl disposed on top of the layer of Ag/AgCl;
collecting data regarding a level of an analyte from signals generated by the sensor;
transmitting the collected data to a display unit; and
displaying an indication of the level of the analyte on the display of the display unit.
