We have developed an effective noncontact technique for the measurement of the electric potential of the human body when performing a stepping motion. This technique is based on the detection of an electrostatic‐induced current generated by the stepping motion. The electric potential of the subject is determined by integrating the electrostatic‐induced current flowing through an electrode that is placed at a distance of 1.5 m from the subject with respect to time. The values of the estimated electric potential are qualitatively in good agreement with those obtained in previous experiments by using an ordinary contact‐type hand electrode.
