Electrostatic charging and discharging have an important impact on the safety and reliability of electronic products, and human static electricity is one of the important sources of electrostatic hazards in the production and use of electronic products. In order to analyze the electrification law of human walking and explore the electrostatic protection measures of human body, the theoretical model of human walking electrification is further deduced on the basis of previous studies. The electrification law of human walking under typical conditions is analyzed, and the influence of maximum foot lifting height on potential is studied. When the maximum lifting height is small, the potential oscillation approximately conforms to the sine law, and with the increase of the maximum lifting height, the sine law is no longer satisfied. When the maximum foot lifting height is small, the actual peak potential cannot reach the saturation potential. Therefore, on the basis of taking electrostatic protection measures, reducing the foot lifting height when walking is helpful to prevent electrostatic hazards.
