Electrochemical sensor
First Claim
1. Electrochemical sensor for determining material concentration comprising a support and an electrode arranged in a region of the support, wherein the electrode comprises a plurality of electrode layers arranged one above another, wherein two of the plurality of electrode layers each comprises a non-conductive parent substance, wherein the non-conductive parent substance of at least one electrode layer has inner hollow cavities within it, wherein at least some of a surface of the inner hollow cavities within the parent substance is coated with a layer of a conductor, and wherein a specific material-recognizing substance is incorporated into at least some of the inner hollow cavities within the non-conductive parent substance of at least one electrode layer.

Abstract
The invention relates to a sensor for detecting substance concentration or activity or for determining the presence of substances based on electrochemical reactions. The electrochemical sensor comprises an electrode with surfaces inside the electrode, wherein electrochemical detection reactions occur. Said sensor guarantees high flow densities and is suitable for miniaturization. A substance-recognizing agent is advantageously placed in the electrode in contact with the inner surfaces. This enables not only short response times and long service life but also measurements with excellent linearity.
