Abstract:
This paper discusses an application of a portable electronic nose based on an array consisting of 8 piezoelectric sensors with nanostructured solid-state coatings to detect volatile biomolecules secreted by nasal mucus and skin. A fundamentally new approach is proposed for a quick assessment of the status of the human body as a whole (normal, stress, inflammation) and the work of individual systems (reproductive, endocrine, digestive), based on the results of the assessment of the qualitative and quantitative composition of the gas mixture of biomolecules secreted by the skin in the Zakharyin-Ged zone. An algorithm is proposed for reading and visualizing signals from an array of sensors understandable to any user. Also, a portable electronic nose was applied in the veterinary field for assessment of the health status of calves’ respiratory system. Unlike the traditional approach in diagnostics using sensor array, one sample of nasal mucus was monitored for 5-9 hours with an interval of 2-3 hours. The integral analytical signal of sensors, in that case, was connected to the microbiological contamination of the sample or its absence. The speed and simplicity of measurement using an electronic nose with nanostructured piezoelectric sensors allow painlessly scanning the body for metabolic disturbances and estimating the presence of certain pathologies as well as the effectiveness of treatment.
