Detection of human walking motion based on measurement system of current generated by electrostatic induction

In this study, an effective noncontact technique for the detection of human walking motion is proposed. The technique involves the measurement of the electrostatic induction current flowing through a measurement electrode. Further, an occurrence model for the electrostatic induction current generated due to a change in the electric potential of the human body is proposed. This model effectively explains the behavior of the waveform of the electrostatic induction current flowing through the measurement electrode. The obtained results show that the degree of fastening of a subject´s foot is directly reflected in the electrostatic induction current generated due to walking motion. This suggests that subtle differences in the walking style can be detected using the proposed technique.
