Assembly of linked electrodes (usually microelectrodes, ultramicroelectrodes or nanoelectrodes) acting as a single electrode.
Notes:
- By replacement of macroelectrodes with dimensions in the millimetre or centimetre range by a microelectrode array, the current density can be increased by orders of magnitude, as well as the ratio of faradaic to capacitive currents. When array electrodes are employed as generator-collector systems with two distinct potentials applied, the diffusion distance between electrodes becomes the main factor in controlling the total current.
- Interdigitated array electrodes are commonly employed in electrochemical sensors.
