Layered sensor for determining an analyte concentration
First Claim
1. A method for producing implantable sensors for determining an analyte concentration in a body tissue or a body fluid, the method comprising the steps of:
- applying a first metal layer substantially over a first plane of a carrier film and a second metal layer substantially over a second plane of the carrier film, the first and second metal layers directly contacting the carrier film, wherein the first and second metal layers comprise first and second electrode contact layers and the first and second planes are spaced apart on the carrier film, the carrier film comprising an insulating material;
providing first and second electrode systems on the respective first and second electrode contact layers; and
cutting the carrier film into a plurality of strips, wherein each strip comprises an implantable sensor.

Abstract
An implantable sensor is provide which can be used for determining a concentration of at least one analyte in a medium, in particular a body tissue and/or a body fluid. The implantable sensor has a layered construction with at least one insulating carrier substrate and at least two electrodes which are arranged in at least two different layer planes of the implantable sensor and are electrically isolated from one another by the at least one insulating carrier substrate. The electrodes have electrode areas which face the medium when the sensor has been implanted, and are in contact with the medium over a large area and substantially uniformly, directly or via a generally analyte-permeable membrane layer.
