In the article a description of the behaviour of metallic layers created in the process of physical vacuum deposition on a composite textile substrates during their cyclical bending process is presented. Either the results of experimental research or the theoretical considerations of changes in the structure resistance as a function of the number of fatigue cycles are presented. It was confirmed mathematically that at the beginning of the bending process, in the case of a small number of bends, single cracks appear on the surface of the layer. After exceeding a certain number of bends, the nature of defects on the surface of the layer changes and the dominating mechanism of changes is the widening and elongation of already existing cracks. It has been confirmed mathematically that changes in resistance in these cases depend respectively on the number of bending cycles and next on quadratic value of number of cycles. A correspondence between the mathematical description and experimental results was obtained.

“…Interdigitated electrodes are made in the form of two individual addressable comb-like interdigitated structures. IDEs form part of a group of transducers widely used in metrology where impedance and capacity changes are essential, e.g., in humidity and gas sensors, and in biosensors for tumor cell and cardiac troponin T biomarker detection or in biomedical applications [ 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 ]. In the literature, there are also reports on the usage of IDEs in sterility tests in the food industry.…”

Staphylococcus aureus is a bacterium which people have been in contact with for thousands of years. Its presence often leads to severe disorders of the respiratory and circulatory systems. The authors of this article present a prototype of a textronic sensor enabling the detection of this bacterium. This sensor was created using a process of physical vacuum deposition on a flexible textile substrate which can be implemented on clothing. With increasing numbers of bacterial colonies, changes in the sensor’s electrical parameters were observed. The sensor’s resistance reduced by 50% and the capacitance more than doubled within the first two days of starting bacterial cultures. Extensive changes in electrical parameters were observed at 100 Hz and 120 Hz of the measurement signal.

“…Thin electroconductive layers formed on flexible substrates may be connected to cloths and used as an integral part of textronic systems used among others in medicine for measurement and monitoring body parameters [3][4][5][6][7][8]. It is also particularly important when textronic structures are a component of sensors monitoring the working conditions for example humidity or gas sensors [9,10]. Before smart textiles, in which the textronic systems are used, high requirements are, on the one hand, connected to the correct structure and, on the other hand, connected to miniaturisation of applied electronics and precision recording and data processing.…”

Technology of creating electrical and electronic systems on flexible substrates, with special emphasis on textile substrates, is one of the most important areas in the field of developing textronics, which is applicable in protective clothes. Resistance and ampacity are the key parameters of electrically conductive thin layers formed on such substrates. Authors of this paper present the results of research related to creation of thin-layered, electrically conductive structures on substrates using a vacuum technology of layer application and assess the scope of their usefulness. Measurement of averaged surface temperature and thermal energy emitted at the surface of the structure will be the subject to metrological evaluation. The authors present developed method with Peltier cells used for measuring the average temperature and emitted heat to evaluate these parameters. The described method allows measurement of average values by matching the dimensions of the cell to the surface. The proposed method avoids possible temperature gradient around the point of measure which occurs in contact methods. The test results also pertain to the determination of the resistance of the test surfaces using a balance of generated thermal power which allows evaluation of the process of creating layers.
