    • L'invention se rapporte à un système d'électrodes pour capteur électrochimique.
      Le système d'électrodes comprend, disposées sur un substrat conducteur (10), une pluralité de micro-disques (22) électriquement connectés au substrat et une électrode génératrice (20) isolée du substrat par une couche isolante (14) et présentant une pluralité d'ouvertures (24) concentriques avec lesdits micro-disques. Une couche conductrique (12) et des connexions (26, 28) permettent la connexion des électrodes à des sources d'énergie. L'électrode génératrice permet de modifier localement, au niveau des micro-disques, les concentrations d'espèces présentes en solution en regard desdites électrodes.
