Impedance is defined as a ratio between voltage and current and it represents the property of a material to resist the flow of electric current. Bioimpedance represents the characteristic of the living beings tissues to resist the flow of electric current, and its measurement provides non-invasive and safe approach for determination of biological tissues electrical characteristics. Some typical bioimpedance measurement applications are determination of body composition and hydration. Determination of body composition and hydration usually include determination of fat and muscle tissue body mass, total body water, extracellular water, intracellular water, and plasma. Electric current behaves differently at low and high frequencies while passing through the tissue and several bioimpedance models are used to describe its effects (e.g. RC model, Cole models, etc.). Bioelectric impedance analysis (BIA) is a set of methods that are used to measure body composition by means of bioimpedance measurement. In this thesis a system for measuring bioimpedance based on the integrated circuit AD5933 was developed. A four-electrode measurement hardware for bioimpedance measurement was developed, along with software for STM32WB55 development system, which manages the EVAL-AD5933EBZ development system. Additionally, a Matlab application with user interface for measurement results processing and visualization was developed. The functionality of the developed system was experimentally verified by measurements on passive electronic components and measurement of the bioimpedance of the hand.
