At the 2022 CES technology show, BMW revealed two new products due to reach customers in the near future: the 2023 iX M60 electric SUV and a 31-inch screen with integrated Amazon Fire TV. But BMW also showed off its wild imagination by unveiling a radical concept called the iX Flow. Based on the iX SUV, the Flow is wrapped in something called E Ink—the material used in the displays of e-readers like the Kindle—which allows it to change color in the blink of an eye.
At the moment, the iX Flow can only shift through shades of white, grey, and black, but BMW suggested that adding vivid colors isn’t out of the realm of possibility. The E Ink wrap consists of millions of microcapsules containing negatively charged white pigments and positively charged black pigments. This microcapsules—which have a diameter equal to the thickness of a human hair—can be stimulated by an electrical field to bring different amounts of each pigment to the surface of the microcapsule, changing the shade of the car.
