This paper describes a non-contact and real-time measurement technique of human body potential using ultra-sensitive electrostatic induction. When a participant moves his/her palm to a position approximately 30 cm away from an electrostatic induction sensor, electrostatic induction current flows transiently. It is clarified whether estimation of the human body potential is possible by simultaneously measuring the velocity of the participant's palm and distance between the participant's palm and sensor. In addition, even when the participant walks at a position approximately 50 cm away from the electrostatic induction sensor, it is confirmed that the estimation of human body potential is possible.
本文提出了一种利用超灵敏静电感应进行人体电位非接触实时测量的技术。当参与者将手掌移动到距离静电感应传感器约 30 厘米的位置时,会产生瞬时静电感应电流。通过同时测量参与者手掌的速度和手掌与传感器之间的距离,来确定是否可以对手掌的静电感应电流进行人体电位的估计。此外,即使参与者在距离静电感应传感器约 50 厘米的位置行走,也可以确认对手掌静电感应电流进行人体电位的估计是可行的。
