Electrical bioimpedance monitoring is an emerging tool for biomedical research. It constitutes one of the diagnostic methods, based on the study of the passive electrical properties of the biological tissues. Whole body bioelectrical impedance analysis (BIA) is widely used by researchers and clinicians as a non-invasive and safe method to estimate body composition and body water volume in children and adults. This paper is a brief study about the various bio impedance applications for determining multi physiological parameters i.e. arterial blood pressure, heart rate variability, cardiac output, breathing pattern, joint movement and blood glucose recognition. Bioimpedance is an effective parameter and is being researched widely. Since BIA is objective, safe, rapid and non-invasive method, it has been used for clinical diagnosis.
