Abstract
<p class="a"><span lang="EN-US">The problem of functional integration of thermal and capacity research methods, which provides the possibility of realizing a new generation of analog frontend of the Internet of Things in the areas of materials science, biophysics and medicine, is solved. Functional integration means the possibility of the use of the same structure for its controlled heating and temperature measurement. For this purpose, instead of discrete resistive heaters and temperature sensors, transistor structures are proposed. This helps to minimize the sizes of measurement transducers, and so the spatial resolution of the transducersbased sensors of thermal analysis. </span></p><p class="a"><span lang="EN-US">The concept of constructing the functionally integrated thermal sensors based on the transistor structures and capacitive signal transducers is developed. The novelty of the proposed sensors of thermal analysis, in addition to measurement of temperature and amount of thermoenergy emitted and absorbed in the object of research, is the possibility of measuring the electrical capacity. This possibility could be particularly assured by the measurement of temperature deformation of a research object or a console that is bent under the effect of the object. </span></p><p class="a"><span lang="EN-US">The new solution of the control scheme of the transistor transformers that support the pulse managed heating and forming the informative signal of the temperature of transistor is proposed. The high precision Analog Devices AD7747 24bit converter is taken as the basis of the capacitive signal transducer.</span></p><p class="a"><span lang="EN-US">The developed transducer provides the managed heating of research objects and is characterized by the high values of temperature resolution (not worse than 0.01 <sup>o</sup>C) and electrical capacity (not worse than 10–16 aF) measurement. </span></p>
