If you accidentally dropped your smartphone and caused the screen to break, you will have two options: take screen repair or buy a new phone.
However, scientists at the University of California (USA) has provided you with a third choice. They have developed a smartphone screen material capable of self-healing scratches on the surface.
According to the Business Insider , scientists have conducted a number of tests on new materials , including self-healing of cuts and scratches. " After being cut to half, the material will be able to self-heal after 24 hours, " said lead researcher Chao Wang.
The new material is also very elastic when it can be up to 50 times longer than the original size due to its plasticity and ionic salts. In addition, the ability to heal scratches of this material comes from a particular type of interaction within it: ion-dipole interaction, a type of interaction between conductive ions and molecules in Each pole. This means that when scratches appear on the material, the ions and molecules will attract each other to reconstitute and bring the material back to its original state.
Wang says this is the first time scientists have created self-renewable materials that can conduct electricity. As a result, this material can be applied as a smartphone screen and battery.
Prior to this, some LG smartphones like the G Flex also had a similar material on the back to heal the scratches themselves. However, LG's materials can not conduct electricity so engineers can not use it as a smartphone screen.
Most smartphone monitors now have a bottom electrode and when users touch, their fingers form a complete circuit with the screen. As a result, your smartphone can tell where you are putting your finger on the screen to give you the right feedback.
Mr. Wang predicts that this new self-healing material will be used as a smartphone and battery monitor by 2020. "Self-healing materials may seem strange in practice, but I believe they will. soon be available on smartphones , "Wang said," In the next 3 years, a variety of material self-healing will be brought to market and changed the lives of us. we will make smartphones It's much better than it is today .
