Devices for measuring components of nonlinear complex resistance heterogeneous objects in operating modes
Abstract
Background. The nonlinearity of the parameters of the complex resistance of heterogeneous objects causes a violation of the principle of superposition, which is observed in homogeneous objects. In this regard, a reliable assessment of the quality of products with a heterogeneous structure is possible only by measuring the parameters of complex resistance with devices for measuring the components of nonlinear complex resistance in operating modes. The purpose of the study is to develop device structures for measuring components of nonlinear complex resistance of heterogeneous objects based on the systematization of operating modes. Materials and methods. Sets of operating modes of heterogeneous objects and components of methods for measuring the components of complex resistance of heterogeneous objects are structured by the method of system analysis. An example of measuring the surface resistance of a transparent conductive coating depending on a number of influencing factors is considered. Results. The systematization of the operating modes of heterogeneous objects when measuring the components of complex resistance and the systematization of methods for measuring the components of complex resistance of heterogeneous objects are carried out. Conclusions. The systematization of the operating modes of heterogeneous objects makes it possible to fully formalize the design process of measuring devices based on a set of device structures for measuring the components of complex resistance and voltage at an object using a power supply of a measuring circuit with abnormal metrological characteristics, which is used in the development of a digital twin for the automated synthesis of functional transparent conductive coatings with specified properties by spray pyrolysis.
