The BMW iX Flow featuring E Ink Makes it to TIME’S 2022 List of Best Inventions

Woodcliff Lake, NJ – November 10, 2022…Today, TIME’s annual list of the Best Inventions for 2022 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.

Color changes 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 the vehicle’s efficiency. This is done by taking into account 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, the dark outer skin will help the vehicle to absorb noticeably more warmth from the sun.

In both cases, selective color changes can help cut the cooling and heating required from the vehicle’s air conditioning. This reduces the amount of energy the vehicle’s electrical system needs. Moreover, it also affects 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, electrophoretic technology needs absolutely no energy to keep the chosen color state constant. Current only flows during the short color-changing phase.

Electrophoretic coloring is based on a technology developed by E Ink. It is most well-known from the displays used in eReaders. The BMW iX Flow featuring E Ink’s surface coating contains millions of microcapsules. That’s with a diameter equivalent to the thickness of human hair. These microcapsules contain negatively charged white and positively charged black pigments. Depending on the chosen setting, stimulation by an electric field causes either the white or the black pigments to collect at the surface of the microcapsule. Ultimately giving the car body the desired shade.
