1. A sensor comprising:

  • a first substrate having a first major surface and a second major surface opposing the first major surface;

    a second substrate having a first major surface and a second major surface opposing the first major surface, the first and second substrates being disposed so that the first major surface of the first substrate is in facing relationship with the first major surface of the second substrate;

    a working electrode disposed on the first major surface of the first substrate;

    a counter electrode disposed on the first major surface of one of the first substrate and the second substrate; and

    an insertion monitor disposed on the second major surface of one of the first substrate and the second substrate, the insertion monitor being configured and arranged to provide a path for electrical current between at least two contact leads of a meter for indication that the sensor has been properly inserted into the meter.
