Development of Multilayer Impedance Sensors for Dynamic Monitoring of Respiratory Rate

In this work, the use of electroimpedance measurements for the creation of respiratory frequency sensors is considered. Functional methods of examination of respiratory organs make it possible to detect respiratory failure well before the first symptoms, as well as to assess the effectiveness of the therapy. Functional research of external respiration is an important part of clinical medicine and is necessary for the diagnosis of pulmonary diseases, evaluation of the effectiveness of treatment of pulmonary pathologies, for obtaining up-to-date information on the course of diseases, Teaching patients how to breathe properly and persuading them to lead a healthy life. But at present, progress in portable monitoring of the respiratory system has stalled due to the lack of accessible comfortable sensors for prolonged monitoring. However, wearable dynamic monitoring devices are actively used in other areas of medical technology. For example, cardiovascular assessment systems have been used successfully in various commercial projects. Similar technologies can be used to control the respiratory system. In this paper, the possibility of using tensors based on electroimpedance measurement as a sensor for assessing the respiration rate in wearable devices was considered.
