ABSTRACT:
An ion sensor includes an electrically conductive substrate, a redox layer coating the surface of the electrically conductive substrate, a barrier layer coating the surface of the redox layer, and an ion-selective layer coating the surface of the barrier layer. The barrier layer functions to prevent migration between the ion-selective layer and redox layer of substances constituting these layers, and to transmit a potential difference produced in the ion-selective layer by contact with an ion from the ion-selective layer to the redox layer.
