1. A method of manufacturing one or more sensors for the in vivo determination of the level of glucose in a sample, the method comprising:
- determining a pattern of conducting material to be disposed on a web of material;
disposing conductive material on the web to form the pattern for one or more in vivo glucose sensors;
disposing sensing layer material on the web; and
cutting the web to produce one or more in vivo glucose sensors, each sensor comprising conductive material, wherein each of the one or more in vivo glucose sensors include a code applied to each sensor, and wherein each applied code is associated with information related to the respective 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.
