Measurement and Evaluation of the Bioelectrical Impedance of the Human Body by Deconvolution of a Square Wave

摘要

In this study, we use the deconvolution of a square test stimulus to replace a series of sinusoidal test waveforms with different frequencies to simplify the measurement of human body impedance. The average biological impedance of body parts is evaluated by constructing a frequency response of the equivalent human body system. Only two stainless-steel electrodes are employed in the measurement and evaluation.
