Abstract: The technology developed by the authors for creating carbon converting elements for molecular electronic motion sensors using screen printing and laser micro-processing is presented. A batch of samples of converting elements with flat and cylindrical channels with different values of the thickness of the working channel: from 36 to 400 microns and a different distance between the electrodes from 55 to 270 microns was made. Seismic sensors were manufactured using manufactured samples, studies of their frequency characteristics were carried out and configurations were established to ensure the maximum value of the conversion coefficient. For the studied geometric range, the conversion coefficient turns out to be higher, the thinner the channel in which the signal is converted, while for the distance between the electrodes there is an optimal value corresponding to the highest value of the conversion coefficient.

Keywords: seismic sensors, electrochemical systems, microfluidics, microstructures, carbon electrodes.
