Abstract

A microelectrochemical sensor includes an energy supply unit and a sensor unit. The energy supply unit is configured to generate electrical energy using a reference fluid. The sensor unit is configured to determine a concentration difference of a chemical species between a measuring fluid and the reference fluid. The measuring fluid has an unknown concentration of the species, and the reference fluid has a known concentration of the species. The sensor unit is electrically connected to the energy supply unit and is designed to determine the concentration difference using the electrical energy from the energy supply unit.
