Stroke is a disease affecting a large part of our society. According to WHO data, it is the second world’s biggest killer, accounting for near six million deaths in 2016 and it is about 30% of the total number of strokes per year. Other patients affected by such a disease should be rehabilitated as soon as possible. As a result of this phenomenon, paresis may occur. Among the devices available on the market there are many rehabilitation robots, but the method of electrostimulation can be used. The authors focused their attention on electrostimulation and commercially available therapies. Using this method, application to people with large hand muscle contracture is difficult. The authors of the work present a solution dedicated to exactly such people. A solution of textronic sensors manufactured on a textile substrate using the technology of physical vapor deposition is presented in the article. As a result of the conducted research, an electroconductive structure was obtained with a low surface resistance value of 1 Ω/□ and high flexibility. It can alternatively be used in hand rehabilitation for electrostimulation of fingertips. The solution is dedicated to people with high hands spasticity for whom it is impossible to put on a rehabilitation glove.

In this paper, the authors describe the distribution of temperatures around electroconductive pathways created by a physical vacuum deposition process on flexible textile substrates used in elastic electronics and textronics. Cordura material was chosen as the substrate. Silver with 99.99% purity was used as the deposited metal. This research was based on thermographic photographs of the produced samples. Analysis of the temperature field around the electroconductive layer was carried out using Image ThermaBase EU software. The analysis of the temperature distribution highlights the software’s usefulness in determining the homogeneity of the created metal layer. Higher local temperatures and non-uniform distributions at the same time can negatively influence the work of the textronic system.

The paper deals with the electromagnetic field shielding both at low and high frequency. At the low frequency the goal of shielding is to regulate the distribution of electromagnetic field in order to either minimizing the power losses in the iron (steel) parts of the device in question. The main practical aim of the shielding at the low frequency electromagnetic field is to avoid the state of overheating. At the high frequency the shielding is mainly dedicated to limit the radiation from the electromagnetic sources and the protection of electronic devices. In some extreme cases the shielding has to protect the humans against electromagnetic field.

The article outlines the assumptions of the theory of torsion fields treated in the scientific community as an element of pseudoscience. This topic is important due to the emergence of conspiracy theories related to the introduction of a new generation of mobile telephony, which is a natural development of technology, and the dissemination of false information about the spread of viruses, including Covid-19. The presented opinion of the authors is a contribution to the educational process aiming at the elimination of the conspiracy theories from the society.

The paper aims at the presentation of controversies and methods of their elimination in bioelectromagnetic research. The concept of post-normal science that gathers the controversial research and non-univocal results, has been described. It was proved that the concept of post-normal science does not lead neither to the eliminating controversies nor to stimulation of researchers to finding the conclusive results. As the panacea for the controversies the filling gaps in our knowledge is proposed. The exemplary gaps have been quoted.
