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 more advanced InterDigitated microelectrodes Array (IDA) consist of two individually addressable microelectrode array strips with an interdigitated approach and a reference as well as counter electrode.  The microelectrodes are available in different sizes and materials (platinum or gold).


The gold layer is 150 nm thick on 50 nm titanium. The cell has a diameter 3.5 mm. There are 20 pairs of 10 µm wide electrodes. The gap between the electrodes is 5 µm.   

Specification - wetted metal materials are either gold or platinum    2020
