A human body is occasionally electrified in a room. This charged object will be a source of electrostatic accidents, including the malfunction of electronic equipment. Hence, prevention of these accidents is required. Accidents occasionally occur, even though antistatic clothes and shoes are used. One of the causes for these accidents is that there is a lack of the preventive measures. This situation occurs when using, for example, unconductive wax. In this study, human body potential (voltage) is measured using a non-contact measuring system. An investigation of the human body's voltage when using this system is conducted. The result demonstrates that the voltage of a human body wearing antistatic clothes and shoes or light clothes and slippers exceeds a malfunctioning voltage of a microelectronics device when the body walks on floors. Thus, accidents may occur even if a human body wearing the antistatic clothes walks on flooring. These results will be useful in estimating determination whether electrostatic accidents occur or not.
人体偶尔会在房间里带电。这个带电物体将成为静电事故的源头，包括电子设备故障。因此，需要预防这些事故。即使使用了防静电衣服和鞋子，事故仍偶尔发生。这些事故的原因之一是缺乏预防措施。例如，使用不导电蜡时就会出现这种情况。在本研究中，使用非接触式测量系统测量人体电位（电压）。对使用该系统时人体的电压进行了调查。结果表明，当人体穿着防静电衣服和鞋子或轻便衣服和拖鞋在地板上行走时，其电压超过了微电子设备的故障电压。因此，即使穿着防静电衣服的人体在地板上行走，也可能发生事故。这些结果将有助于估计是否会发生静电事故。
