In this paper, we present the results of the simulated behavior and experimental measurement of the chemical potential or potential interaction for a raw ceramic phase structure (Al2O3(ZnO/SnO2)+Ti0,1O2) used the theoretical model of multiples single harmonic oscillators. The above results were obtained considering the application of such materials by contact field sensors. In turn, was taken as the approximate basis for the interaction potential as a nonlinear function of: temperature, relative electric permittivity, relative humidity, type ofcharge carriers(n) and(p) of the material and surface voltage. On the other hand, was calculated and simulated the electrical behavior responsible for the chemical potential energy propagation in the structure of the compound under study.
