When a low-level alternating electrical current is applied to a biological system, a voltage drop or impedance to the electrical flow is detected. Conductance, which is the opposite of impedance, is greatest in the electrolyte-rich body water and is lower in lipids and bone mineral. Two sets of electrodes at defined locations on the animal serve for the measurement of the impedance. In addition, body weight and the distance between detector electrodes are measured. Because this system is portable, inexpensive, and simple to operate, it is frequently used to estimate the fat-free mass in humans and in animals as well.
