MotorAuthority je napisal/-a:Paramagnetic paint changes color at the touch of a button

Posted on Wednesday 7 November 2007
One of the hardest decisions when picking a new car is choosing the right color but the day when cars will be available in multiple colors could be here sooner than you think. Scientists have developed a new coating called ‘paramagnetic’ paint that has the ability to change colors at the touch of a button. One carmaker looking into the technology is Nissan, which has already developed a self-healing paint.


Before the vehicle is painted, a special polymer containing the special ‘paramagnetic’ iron oxide particles is applied to the car’s body. An applied electric current then adjusts the spacing of small crystals within the iron oxide particles and therefore affects their ability to reflect light and change color.

The process is perfect for metal objects like cars because a continuous small current is needed to maintain the desired color. When the vehicle is switched off, the car returns to a default color of white.

The coating has the ability to reproduce any color visible to the human eye and it takes less than a second to change the entire car. The first commercial applications could be on the market as early as 2010.

New ‘smart’ materials to revolutionize car design

Posted on Wednesday 7 March 2007
General Motors recently demonstrated its latest development in the field of smart materials during a media event at its R&D center. New technologies such as shape memory alloys and polymers are just some of the new materials that GM is investigating for future use in its cars. The materials get their name from their ability to change shape, stiffness or strength when either heat, stress, electric current or a magnetic field is applied and can then return to its former state when the stimulus is removed.

These new materials could eventually lead to many possible movable features in cars, and we may even see the first production examples as early as 2010. Such possibilities include buttons and handles that automatically pop out when required, active surfaces that can move depending on vehicle speed to aid aerodynamics, and light-weight actuators and sensors that could replace the heavy motors and hydraulic systems found in today’s cars.
GM’s executive director of R&D Alan Taub also hinted at the possibility of vehicles that can self-heal in the event of damage, or can be designed to change color or appearance at the touch of a button.
