ます。(Conventional technology) E-electricity occurs when a material has a large resistance value. Plastics such as polyvinyl chloride and polyethylene generally have a large resistance value and high insulation properties, so static electricity is likely to occur. This causes dust to attract, stick, repel, and cause electric shock, and an explosion of electromagnetic waves is emitted due to discharge, causing computer malfunctions and circuit destruction.

The resulting automotive doorknob cover has a half-life of 0 seconds, a frictional charge voltage of 15 V, a surface leakage resistance of 2 x 10'Ω, and an e of 20,000 V or less.
It was possible to neutralize the electricity by discharging it in the air for a period of time. You can also use this n-vehicle door/cover to reduce humidity up to 20%.
Although the door was repeatedly driven in and out of the car during a very cold period, there was no electric shock caused by static electricity, and there was no damage to the doorknob cover, so it was possible to use the door continuously.
