Abstract
The invention relates to an electrochemical sensor for the determination of a concentration of at least one analyte in a medium, in particular a body tissue and/or a body fluid, to an apparatus that includes the electrochemical sensor, and to a use of the electrochemical sensor, and finally to a method for producing it. The electrochemical sensor has an isolation element and at least two electrodes. The at least two electrodes comprise at least one working electrode and at least one further electrode, in particular at least one counter electrode and/or at least one reference electrode. The at least two electrodes run parallel to one another and form an electrochemical measuring cell of the electrochemical sensor.
