1. A method for manufacturing a sensor for detecting an analyte in a body fluid, the method comprising steps of:
providing a membrane layer;
forming at least one electrode pad of a working electrode by depositing at least one chemical reagent onto a region of the membrane layer and depositing a first electrically conductive material onto the at least one chemical reagent;
forming an electrically conductive lead on the at least one electrode pad of the working electrode;
forming at least one electrode pad of a further electrode, wherein the further electrode is chosen from the group consisting of a counter electrode and a reference electrode, by depositing an electrically conductive material directly onto the membrane layer;
forming an electrically conductive lead on the at least one electrode pad of the further electrode; and
depositing an electrically insulating material onto the membrane layer, the at least one electrode pad of the working electrode, the electrically conductive lead of the working electrode, the at least one electrode pad of the further electrode and the electrically conductive lead of the further electrode to form the sensor.
