• Body surface with real color change thanks to electrophoretic technology named to TIME’s List of Best Inventions for 2022.
• Potential for future interior and exterior applications.

Woodcliff Lake, NJ – November 10, 2022…Today, TIME reveals its annual list of the Best Inventions for 2022, which features 200 extraordinary innovations. To compile the list, TIME solicited nominations from TIME’s editors and correspondents around the world, and through an online application process, paying special attention to growing fields such as the electric vehicle industry, green energy, and the metaverse. TIME then evaluated each contender on a number of key factors, including originality, efficacy, ambition, and impact.

Of the new list, TIME’s editors write, “The result is a list of 200 groundbreaking inventions (and 50 special mention inventions) including life-mapping artificial intelligence, diamonds made from excess carbon in the air, and the most powerful telescope ever that are changing how we live, work, play, and think about what’s possible.

The full list is available here: time.com/best-inventions-2022

Color change at the touch of a button.

The BMW iX Flow featuring E Ink is a unique vehicle capable of changing its entire body color at the touch of a button and was first revealed at the Consumer Electronics Show 2022 in Las Vegas. By making it possible to alter the body color and display different patterns, the BMW iX Flow opens up a whole new way of personalizing the driving experience.

A variable exterior color can also contribute to wellness in the interior and to the efficiency of the vehicle. This is done by taking account of the different abilities of light and dark colors when it comes to reflecting sunlight and the associated absorption of thermal energy. A white surface reflects a lot more sunlight than a black one. By implication, heating of the vehicle and passenger compartment as a result of strong sunlight and high outside temperatures can be reduced by changing the exterior to a light color. In cooler weather, a dark outer skin will help the vehicle to absorb noticeably more warmth from the sun.

In both cases, selective color changes can help to cut the amount of cooling and heating required from the vehicle's air conditioning. This reduces the amount of energy the vehicle electrical system needs and with it also the vehicle's fuel or electricity consumption. In an all-electric car, changing the color in line with the weather can therefore also help to increase the range. In the interior, the technology could, for example, prevent the dashboard from heating up too much.

E Ink technology itself is extremely energy efficient. Unlike displays or projectors, the electrophoretic technology needs absolutely no energy to keep the chosen color state constant. Current only flows during the short color changing phase.

Millions of paint capsules in a custom wrap.

Electrophoretic coloring is based on a technology developed by E Ink that is most well-known from the displays used in eReaders. The surface coating of the BMW iX Flow featuring E Ink contains many millions of microcapsules, with 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 electrical field causes either the white or the black pigments to collect at the surface of the microcapsule, giving the car body the desired shade.

I wouldn't call this color changing but rather shading.

I guess you could put two opposing colors in the capsules like red and yellow and apply half voltage to get a green car

Interesting technology (which is not new, BTW, just on a car), but I'm guessing several years out until someone markets it practically for a color-changing car. And it might not be BMW. It's a solution in search of a problem, but in this case a good one, and remains to be seen where or if it goes beyond gee-whiz, looky what we can do....

I thought it was cool when they first introduced it but sincerely forgot this tech even existed in the interim. Hard to understand how this would be used by anyone - perhaps for advertising by having a moving billboard.
