Double-metal thin-film electrochemical sensors are based on a three-electrodes approach with a gold working electrode (WE) and platinum reference (RE) and auxiliary (AE) electrodes. The combination of two different metal electrodes in the same EC cell enables the modification of the working electrode surface selectively without affecting the surface of the reference and auxiliary electrodes.

Thin-film technologies enable the development of small microstructures (<25 µm) with high resolution and precision. Thus, a microelectrode array (MEA) based on pinholes with a honeycomb microstructure can be manufactured on a working single-electrode. The working electrode (1 mm diameter) is based on a metal surface coated with SU-8 resin in which is defined a microholes array with honeycomb structure. Thin-film MEA electrodes show the typical microelectrode behavior to enhance the analytical signals by reaching the steady-state in a short time.

Thin-film technologies enable the fabrication of microelectrodes (<25 µm) with high resolution and precision. The most basic interdigitated electrodes (IDE) consist of two individually addressable microelectrode array strips with an interdigitated approach. Non additional reference and auxiliary electrodes are included on the device. Different interdigitated electrode (IDE) designs are available in platinum or gold.

Thin-film technologies enable the integration of the reference (RE) and auxiliary (AE) electrodes with the interdigitated microelectrodes. Interdigitated array (IDA) electrodes take also advantages of the microelectrodes features enhancing the sensitivity and detection limits. In this case, the working electrode (WE) consists of two individually addressable arrays of microelectrodes with an interdigitated approach. Different IDA microelectrode (WE1/WE2) designs are available in platinum or gold.

Thin-film IDA electrodes could be used in single- (only one WE, generator, is connected) or dual-mode (both WEs, generator and collector, are connected). Dual-mode enables the microelectrode behavior, reaching the steady-state in a short time and enhancing the analytical signals. Redox cycling performed at Interdigitated Array (IDA) microelectrodes IDA microelectrode designs (width and gap) are going to affect the number of redox cycling as well as the collection efficiency.
