Engineering360: "Electrostatic atomizer efficiently paints Toyota’s vehicles"

"Powder" painting has been around for years and hot rodders have used it for painting vehicle chassis for years.

I believe this is a wet paint application.

From the source article, "Electrostatic atomization technology is used in beauty treatment devices and other instruments that spray fine amounts of liquid; here, we applied it to vehicle body painting."

The addition of current control and a spinning, grooved nozzle took some real ingenuity to conceptualize and perfect, and is an admirable move forward in production painting efficiency. I hope it propagates.
