This letter presents a method for visualizing the 2-dimensional distribution of electrostatic charge, which is based on the principle of the X-ray CT. For confirming the possibility of this method, the focusing images of the simple model are also demonstrated by a computer computation.

This letter describes the potential attenuation mechanism of the charged human body due to walking on the polymer floor. A model is proposed for analyzing the human body potential. The validity is verified by measuring the potentials of the charged acrylic sheet.

This letter presents a method for real-time visualization of static electricity distribution which can be achieved by rapidly measuring the voltages induced on the array electrodes. For verifying the validity of this method, the measurement examples on the charged sheets are demonstrated.
