Thermoelectric device with electronic control unit for diagnostics of inflammatory processes in the human organism

Abstract

There are a large number of high-efficiency optical devices based on thermocouple sensors for radiometric measurements, e.g. Angstrom compensating pyrheliometers, etc. [1][2][3]. However, in this paper, heat fluxes were measured using gradient semiconductor thermoelectric sensors that have a narrow specific application in medical and biological thermometric measurements [4][5][6][7][8].The peculiarity of such sensors is that they do not require compensation heaters, which can distort the temperature and heat flux distributions of the biological objects under study.Semiconductor thermoelectric sensors of heat flux [9][10][11][12][13][14][15], which combine miniaturization, high sensitivity, stability of parameters in a wide range of operating temperatures and compatibility with modern electronic recording equipment, are known to be promising for testing human local heat release. The use of such sensors allows achieving high locality and accuracy of thermometric measurements. This, in its turn, makes it possible to obtain information on the characteristics of the objects under study and analyze them in detail in order to identify the inflammatory processes of the human body at an early stage.An important factor in the study of human body heat fluxes with the help of such sensors is the accuracy and speed of recording the signals of thermoelectric sensors. Previously developed thermoelectric devices with electronic control units [16][17][18][19][20] have certain drawbacks, the main one being the dependence of the thermoelectric sensor readings on the ambient temperature.
