1. A method of making an electrochemical sensor, the method comprising:
- providing a substrate having a sensor planform having a first portion and an adjacent second portion;
applying at least one contact pad to the second portion;
applying at least one conductive trace to the first portion and to the second portion such that the at least one conductive trace electrically communicates with the at least one contact pad;
applying a sensing layer over at least a portion of the conductive trace; and
removing the sensor planform from the substrate to form a removed sensor;
wherein the sensing layer comprises an electron transfer agent.

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.
