The purpose of our study was to evaluate the dielectric characteristics of the skin that occur during pregnancy in an experiment. The study included 60 Wistar rats, 30 of which were pregnant (in the 3rd trimester; parturition took place 2–3 days after the study). Once, on a pre-epilated area of the skin of the back, the dielectric properties were studied using the method of near-field resonant microwave sensing. The diagnostic software and hardware complex for microwave sensing allows calculating the level of dielectric permittivity of the medium and conductivity based on the shift of the resonant frequency. Based on the conducted studies, it was found that the integumentary tissues of pregnant rats have a significantly higher level of dielectric permittivity and conductivity compared to non-pregnant animals. Such shifts are caused by the formation of edematous syndrome associated with pregnancy, and predispose to the development of postpartum skin changes.
