What is it about?
Electrical bioimpedance (EBI) of a material, in this case, tissue, organs, or human body parts, is presented in a raw form as magnitude and phase angle, real and imaginary components, resistance and reactance, or the dielectric (physical) parameters like complex permittivity or conductivity. In medicine, this identification should be associated with disease stage, physiological, physical, chemical, or biological, differentiation or evolution over time.

Why is it important?
The outline of this chapter is focused mainly on the application of the electrical bioimpedance technique and its relation or usefulness for medical diagnosis. The signal analysis performed for this purpose is mentioned in each case, but the progress of signal analysis methodologies in time is not addressed. Final remarks about the signal analysis are revisited at the end of the chapter.
Perspectives
Health professionals and related sciences should recognize electrical bioimpedance as a novel, non-invasive technique for the diagnosis and prognosis of very diverse pathologies, such as those related to pathologies of the gastrointestinal tract among many other applications.
