Properties (II) of Human Body Charge Electrified by Walking

Abstract

Most obstacles of electronic equipments due to electrostatic discharge (ESD) are well-known to be caused by the electrification phenomena appearing with the human body walking, while this mechanism has not sufficiently been elucidated. For taking drastic measures against the ESD, it is necessary to understand both the occurrence-charge behaviors and human-body capacitance in relation to walking actions. From this point of view measurements of the occurrence charges and human potentials are made. The electrification properties are examined statistically for the furdamental walking-motions. The pace transitions of the human-potentials due to continuous walking and stepping are also shown and their prediction models are presented.
