| 摘要 |
The system concerns an electrode system for an electrochemical sensor, comprising, arranged on a conductive substrate ( 10 ), a plurality of micro-discs ( 22 ) electrically connected to the substrate and a generating electrode ( 20 ) insulated from the substrate by an insulating layer ( 14 ) and including a plurality of orifices ( 24 ) concentric with said micro-discs. A conductive layer ( 12 ) and connections ( 26, 28 ) enable to connect the electrodes to power sources. The generating electrode enables to modify locally, at the micro-discs, the concentrations of species present in solution opposite said electrodes.
