Stimuli-sensitive hydrogels change their volume significantly in response to small alterations of certain environmental conditions. The combination of both sensor and actuator properties probably allows the simplest realization of an active device for automatic concentration regulation of chemical substances. Because of its functionality, this apparatus is, ultimately, a chemical comparator or chemostat. Automatic flow control depending on ion and solvent concentrations in aqueous solutions has…
