1. An analyte sensor for implantation in a body for use with a slotted needle, the sensor comprising:

  • a substrate with notches cut in the substrate to form a necked down region in the substrate and a non-necked down region in the substrate wherein the non-necked down region is distal to the notch which forms the necked down region and is for placement within the body; and

    at least one sensor electrode formed from one or more conductive layers,wherein the notches creating the necked down region allow the substrate to slide into the slotted needle that has a slot narrow enough to permit passage of the necked down region, but prevents the non-necked down region of the substrate from slipping out of the slotted needle, andwherein the notches cut in the substrate do not expose any sensor electrode to analytes.
