METHOD OF MAKING AN ELECTROCHEMICAL SENSOR
First Claim
1. A sensor for the in vitro determination of the presence and/or level of glucose in a sample, the sensor comprising:
- a substrate comprising a depression therein;
a working electrode formed in the depression; and
a contact pad to couple with a processing unit,wherein the in vitro sensor is configured to determine the presence and/or level of glucose in a volume sample of about 1 microliter or less.

Abstract
A process for the manufacture of small sensors with reproducible surfaces, including electrochemical sensors. One process includes forming channels in the surface of a substrate and disposing a conductive material in the channels to form an electrode. The conductive material can also be formed on the substrate by other impact and non-impact methods. In a preferred embodiment, the method includes cutting the substrate to form a sensor having a connector portion and a transcutaneous portion, the two portions having edges that define one continuous straight line.
