Abstract
The aim of the paper is to investigate the changes in electrical parameters of the interdigitated electrodes (IDEs) due to the development of Staphylococcus aureus. More precisely, the article presents the results of electrode's resistance, capacitance and inductance changes in the function of bacteria density. The electrodes are made in the process of physical vacuum deposition on composite textile substrates. This allows to apply them in textronic applications. Changes in the electrical parameters of the produced IDEs were observed during microbial cell culture growing. The results of the research have demonstrated that the bacteria density influences the electrical parameters of the electrode. The greatest changes in these parameters are observed at the frequencies of 100 and 120 Hz after the day of inoculating staphylococcal cells into the medium, where the measuring electrodes were placed.
