Biological impedance analysis bia
WebBioelectrical impedance analysis (BIA) is a safe, practical, and non-invasive method for measuring components of biological tissues and biological materials [1-4]. BIA relies on the conduction of radio-frequency electrical current by the fluid (water, interstitial fluid, and plasma), electrolytes, and WebJan 1, 2012 · Electrical impedance comprises both the opposition to current related to resistance and reactance. In Cartesian form, electrical impedance can be defined as. Z=R+jX\text [\Omega ]. (3.5) where Z denotes impedance, j is an imaginary unit (\sqrt {-1}) and is used instead of i to avoid confusion with the current symbol.
