1. A method of manufacturing one or more sensors, the method comprising:
- forming an electrode pattern on a continuous web;
disposing sensing layer material on the web;
disposing a biocompatible layer on the web;
disposing a mass transport limiting layer on the web; and
cutting the web to produce one or more sensors, wherein each produced sensor is configured for the in vivo determination of a level of glucose in a sample and wherein each produced sensor is capable of operation for at least three days.

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.
