Measuring electrode for measuring a concentration of a substance in a tissue fluid, measuring device and method for manufacturing a measuring electrode for measuring a concentration of a substance in a tissue fluid

The invention relates to a measuring electrode (100) for measuring a concentration of a substance in a tissue fluid. The measuring electrode (100) has a carrier layer (102) to the at least one microneedle (104) is arranged. The microneedle (104) is formed to anchor the measuring electrode (100) in a tissue fluid having the tissue. Furthermore, the measurement electrode (100) at least in sections on the microneedle (104) and / or the carrier layer (102) applied detection layer (112) for electrochemically detecting the substance.
