Background. The paper considers the presented analytical model, which summarizes the parameters of piezoelectric materials due to the influence of various physical quantities (electrical, mechanical, thermal, radiation and chemical). Materials and methods. To obtain a systematized model, a graph model is used that clearly demonstrates the mechanisms of the material's responses to external influences. Results. Based on the obtained model, a group of equations is presented that allows introducing additional errors in studies related to piezoelectric materials. Conclusions. The proposed method of consideration of measurements using piezoelectric materials allows us to form general ideas about such experiments, as well as significantly improve the accuracy of calculations and technical characteristics of sensor equipment as a whole.
