Abstract:Bioelectrical impedance analysis (BIA) involves passing a weak, high-frequency current through the body in order to measure variables such as tissue volume, or the volume of blood, on the basis of electrical resistance. Biometric measurements using BIA date back to the beginning of the 20th century; and since then there have been many technical refinements. BIA is non-invasive, it excels in terms of cost and safety, and it does not require any special measurement skills. It has therefore become an outstanding … Show more
