OnePlus 8T Concept, a color-changing smartphone that will track your breathing For many years, new smartphone models have focused mainly on offering faster processors and larger displays than their predecessors.

Fortunately, this topic is changing a bit and recently we have seen at least some innovative designs from LG, such as the Wing model with an additional rotating screen that can be turned by 90 degrees to create something like the letter T. We are also seeing devices with folding flexible displays, and now OnePlus has presented a concept smartphone that attracts attention with some interesting functionalities. First of all, its housing can change color, and secondly, there is a millimeter wave radar (mmWave) inside.

As the name of this device suggests, its base is the well-received OnePlus 8T model that the company presented a few months ago. As for his ability, borrowed from chameleons, it is Electronic Color, Material and Finish (ECMF) technology, which uses a film containing a metal oxide placed under glass and changing color depending on the voltage. The housing can change the color from silver to blue and black, which in combination with an interesting etched glass pattern gives a very interesting effect. What's more, it has a practical application, because it can serve as a kind of notification LED, e.g. black color when someone calls us.

As for the second option mentioned, the OnePlus OnePlus 8T Concept has millimeter wave radar (mmWave), which allows you to "perceive, image, locate and track" everything in the environment. This is similar to the Motion Sense technology from the Pixel 4 model, which detects hand movements, so we can mute the alarm with special gestures, switch songs or reject a call without having to touch the phone. And although it can hardly be called a revolution and Google decided to abandon this option with Pixel 5, the company announces that it will return to it, so perhaps the market was simply not ready for it. As if that was not enough, OnePlus decided to combine both innovations, i.e. color change and radar, using them together to monitor the user's breathing - the radar tracks the chest movements and calculates the rhythm of our breathing, and the housing signals the result with color. The only question is whether the manufacturer will decide to debut this device on the market, or whether it is only a demonstration of the possibilities.
