This thin-film sensor has a two interdigitated electrodes.
Thin-film technologies enable the fabrication of microelectrodes (<25 µm) with high resolution and precision. The interdigitated electrodes (IDE) provide a suitable tool specially useful for impedance, capacitance and conductivity measurements as well as fuel cells. The most basic InterDigitated Electrodes (IDE) consist of two individually addressable microelectrode array strips with an interdigitated approach. No additional reference and auxiliary electrodes are included on the device. The microelectrodes are available in different sizes and materials (platinum or gold).
The platinum layer is 150 nm thick on 50 nm titanium. The cell has a diameter 3.5 mm. There are 180 pairs of 5 µm wide electrodes. The gap between the electrodes is 5 µm.
Please note that one of the Micrux cells is necessary to connect the electrode.
