CSE 2022: Chameleon in BMW! Save tangled people in an instant

News on January 6 that BMW showed a new car that can change color at this year's CES. With the push of a button, the body color changes instantly, which is very cool.

The car is named iX Flow, and the car uses electrophoresis technology from E Ink. The car's surface coating contains millions of microcapsules, which are as thick as a human hair. Each of these microcapsules contains negatively charged white pigments and positively charged black pigments.

Depending on the setting chosen, the white or black pigments are concentrated on the surface of the microcapsules by stimulation of the electric field, giving the car body the desired color. Currently colors are limited to white, black and grey.

BMW is not studying this technology just to be cool, but to improve the efficiency of electric vehicles. BMW said, "White surfaces reflect sunlight more than black surfaces." This means that by changing the exterior to a lighter color, the heating of the vehicle and passenger compartment due to strong sunlight and external heat can be reduced. In cooler weather, the darker hues will help the vehicle absorb more of the warmth from the sun. ”

But at present, this technology is still in the conceptual stage and has not been put into production, and there are readers who like it who can continue to pay attention.
