The 8T Concept changes the back of the case based on certain events or sensor signals. So far, the color can only be changed from dark blue to silver.
Color change is available thanks to ECMF, Electronic Color, Material and Finish technology. Working principle: the device uses a special film based on metal oxide. It can change color under the influence of voltage. Accordingly, depending on the situation, different voltages are applied, and the smartphone changes color to another.
So far, this is only development. The company does not specify if such smartphones will go into mass production.
But, the company is already seeing several practical uses. For example, by changing the color, you can inform the user about incoming messages or missed calls.
There is also an idea to synchronize the color change with the wearer’s breathing rhythm. For this, special millimeter-wave sensors must be used.
