Production of electrical contact with skin

A measuring, apparatus comprising:

• at least one electrode configured to produce electrical contact with the skin, an electrode of the at least one electrode comprising:
• a first electrical connection;
• a second electrical connection that is electrically insulated from the first electrical connection;
• a skin contact comprising a first contact region and a second contact region, the first contact region being electrically coupled to the first electrical connection, the second contact region being directly adjacent to and electrically insulated from the first contact region and being electrically coupled to the second electrical connection;
• and a support element comprising an adhesive layer on a side of the support element configured to face the skin when the electrode is configured to be in a state placed on the skin and a recess portion with an inner contour having a shape of an outer contour of the skin contact, wherein the skin contact is arranged in the recess in the support element, wherein the skin contact is configured to produce electrical contact between the skin and the skin contact when the electrode is configured to be in the state placed on the skin, wherein the first electrical connection, the second electrical connection, or the first electrical connection and the second electrical connection are arranged on a portion of the support element separate from the recess portion, wherein the first electrical connection is coupled to the first contact region by a first flexible, electrically conductive link, wherein the second electrical connection is coupled to the second contact region by a second flexible, electrically conductive link, and wherein the first electrical connection and the second electrical connection are in essentially semicircular form and are arranged next to one another such that an essentially circular connection device is formed;
• a plurality of measurement connections that are coupleable to one electrode of the at least one electrode;
• and a plurality of auxiliary connections that are coupleable to one electrode of the at least one electrode.
