A human body composition analyzer was designed in the paper based on the principle of bio-electrical resistance, which consisted of 5 sectors including the upper computer, micro printer, weight measurement circuit, electrodes and the impedance measurement circuit. Through detection of the weight and impedance parameters, the hardware and software system of the analyzer were designed with the adoption of the principle of phase sensitive detection. According to the experimental evaluation, the analyzer proved its high accuracy of measurement and conformity to the intended design standards, which could be widely applied in human health examinations.
