Method of Making an Electrochemical Sensor

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.

What is claimed is: 
     
         1 . A process for the manufacture of a sensor, comprising the steps of:
 providing a substrate;   forming one or more channels in one or more surfaces of the substrate; and   disposing a conductive material in the one or more channels to form one or more electrodes, thereby producing a product sensor.
