BMW showed off their new color-changing paint tech at the 2022 CES. Relying on E Ink, the e-paper tech in e-readers, the color-changing paint tech is coming on BMW iX In CES.
The surface coating of the BMW iX Flow featuring E Ink contains many millions of microcapsules, a diameter equivalent to the thickness of a human hair. Each of these microcapsules contains negatively charged white pigments and positively charged black pigments. Depending on the chosen setting, stimulation by means of an electric field causes either the white or the black pigments to collect at the surface of the microcapsule, giving the car body the desired shade.
The innovative paint scheme can be changed with a button, currently, the colors are white, black, and grey. Despite that, BMW says it could have implications for the efficiency of its electric vehicles with heat radiation on different body colors
