Thin-film interdigitated sensor

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. Non 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 90 pairs of 10 µm wide electrodes. The gap between the electrodes is 10 µm. 


Please note that one of the Micrux cells is necessary to connect the electrode.

Specification - wetted metal materials are either gold or platinum    2022
