Human Bioelectrical impedance Measuring Method Based on Principle of Multi-frequency and Multi-segment

摘要：

In the traditional human bioelectrical impedance measurement methods, measurement approach is simplex and accuracy is low.A multi-frequency and multi-segment human bioelectrical impedance measurement method is proposed , which adopts eight electrodes segments measurement technique and direct frequency synthesis method to produce multi-frequency excitation signal, and then achieves multi-frequency and multi-segment measurement of bioelectrical impedance.The results of experiments show that this method effectively improves the measurement accuracy; the relative error of measured impedance magnitude is less than 1％ while the absolute error of phase is less than 1 degree.
