METHOD AND DEVICE OF DETERMINING HUMAN PSYCHOPHYSIOLOGICAL STATE Russian patent published in 2023 - IPC A61B5/507 A61B5/16 G01N21/31 G01N21/47 G01N33/487 

FIELD: medicine.

SUBSTANCE: group of inventions relates to a method of determining the psychophysiological state of a person and a device for its implementation. Detection of sub-terahertz 0.03–1 THz, terahertz 1–30 THz radiation scattered by the individual under study is carried out. Illumination of sweating zones of the studied individual is carried out by electromagnetic oscillation of the sub-terahertz, terahertz frequency ranges with a power that is obviously below the level of permissible safe values, namely, not more than 200 μW/cm²/h. The frequency of the backlight generator is changed. The construction of the absorption spectrum of electromagnetic oscillations in the areas of sweating is carried out. The frequencies of the measured absorption lines are compared with the frequencies of the spectral lines of the substances that make up the sweat. The list of substances detected by probing and being markers of the psychophysiological state is determined. The psychophysiological state is determined by the set and amplitudes of the spectral lines of the markers. The device for determining the psychophysiological state of a person contains a generator of electromagnetic backlight oscillations, a scanning antenna, a detector, a measuring unit, a frequency control unit for the backlight generator, a unit for forming the frequency spectrum of the reflected signal, a unit for analyzing the component composition of sweat, a bank of values for the frequencies of the spectral lines of the components of sweat markers, and also a block for determining the psychophysical state by the spectral composition of sweat, which is connected to the indicator of the psychophysiological state.

EFFECT: remote non-contact control of the psychophysiological state of a person is provided by spectral analysis of the composition of sweat.
