A Trial to Detect for Human Locomotion Based on Measurement of Current Generated by Electrostatic Induction

Abstract

In this study, an effective noncontact technique for the detection of free-living human locomotion 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 presence of a gait cycle is directly reflected in the electrostatic induction current generated due to walking motion. This suggests that subtle differences in the walking condition can be detected using the proposed technique.
