“…As the device will be in sleep mode at most times, the biggest impact on the power consumption is sleep current consumption [32]. In order to minimize current consumption in sleep mode, power to the measurement circuitry is turned off using DIO7929 high side switch, which allows the nRF52 chip to be the only chip that is left powered in sleep mode.…”

In the era of miniaturization of electronic equipment and the need to connect sensors with textile materials, including clothing, the processing of signals received from the implemented sensors becomes an important issue. Information obtained by measuring the electrical properties of the sensors must be sent, processed, and visualized. For this purpose, the authors of this article have developed a prototype of a data collector obtained from textronic sensors created on composite textile substrates. The device operates in a system consisting of an electronic module based on the nRF52 platform, which supports wireless communication with sensors using Bluetooth technology and transmits the obtained data to a database hosted on the Microsoft Azure platform. A mobile application based on React Native technology was created to control the data stream. The application enables automatic connection to the selected collector, data download and their presentation in the form of selected charts. Initial verification tests of the system showed the correctness and reliability of its operation, and the presented graphs created from the obtained data indicate the usefulness of the device in applications where measurements and recording of impedance, resistance, and temperature are necessary. The presented prototype of a data collector can be used for resistance, impedance, and temperature measurements in the case of textronic structures but also in other wearable electronic systems.

“…The production of elastic electronics is possible in spray coating processes using carbon nanotubes, graphene flakes or nanofibers, electroless plating, sputtering, physical vacuum deposition, plasma coating or digital printing 4,[8][9][10][11][12][13] . To fabricate the electroconducting elements on or in textile substrates the varied methods are usually used: the embroidery 14 , dip coating 15 , electrospinning 16 , electroless plating 17,18 , ink-jet or screen printing method 19,20 , thin metallic wires or yarns 3 , metal-coated fibres 21,22 , conductive fibers produced by doping intrinsically conductive polymers 23 , the fibers with metallic core and the outer polymer coating, and even with the liquid metal core 24 , sputtering [25][26][27] or chemical and physical vacuum deposition 2,7 . The 3D printing method is also used to direct deposition of electroconductive architectures on textiles.…”

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.

“…Since cardiovascular diseases have been recognized as the leading cause of patient death globally, medical electrodes enabling the measurement of biological signals, such as in electrocardiography (ECG), have been extensively researched [ 1 , 2 ]. Integrating medical electrodes into wearable devices in particular makes it possible to remotely monitor patients’ health, thereby providing essential information as a means to diagnose diseases in their early stages [ 3 , 4 ].…”

Patch-type hydrogel electrodes have received increasing attention in biomedical applications due to their high biocompatibility and conformal adherence. However, their poor mechanical properties and non-uniform electrical performance in a large area of the hydrogel electrode should be improved for use in wearable devices for biosignal monitoring. Here, we developed self-adherent, biocompatible hydrogel electrodes composed of biodegradable gelatin and conductive polymers for electrocardiography (ECG) measurement. After incorporating conductive poly(3,4-ethylenedioxythiophene):poly(4-styrenesulfonate) (PEDOT:PSS) into gelatin hydrogels crosslinked by natural crosslinkers (genipin), the mechanical properties and electrical conductivity of the hydrogel electrodes were improved and additionally optimized by adjusting the amounts of crosslinker and PEDOT:PSS, respectively. Furthermore, the effect of dimethyl sulfoxide, as a dopant, on the conductivity of hydrogels was investigated. The gelatin-based, conductive hydrogel patch displayed self-adherence to human skin with an adhesive strength of 0.85 N and achieved conformal contact with less skin irritation compared to conventional electrodes with a chemical adhesive layer. Eyelet-type hydrogel electrodes, which were compatible with conventional ECG measurement instruments, exhibited a comparable performance in 12-lead human ECG measurement with commercial ECG clinical electrodes (3M Red Dot). These self-adherent, biocompatible, gelatin-based hydrogel electrodes could be used for monitoring various biosignals, such as in electromyography and electroencephalography.
