hydrogel display: water for wearable devices – Mobile Magazine

The first display of hydrogel is made for more than 90% water. Soft, flexible, elastic and is also wearable. A real super wearable technology. His debut took place with video games and writing programs and opens the way for the development of flexible and wearable devices, with many applications.

It was developed by the dell ‘group National University Seoul coordinated by Chong-Chan Kim, according to the magazine writes Science .

the study of elastic or foldable display is not something entirely new. The researchers in the past have worked on multiple types of conductors, such as carbon nanotubes and the metal nanowires. These, however, are however all based on hard materials. That’s why scientists have developed a display made of hydrogel, ie a network of polymers that tend to absorb water, soft and elastic. They used a hydrogel with the salts of lithium chloride, which act as a conductor and help retain water.

The display on the arms , scholars have been able to write words, play the piano and play games. The device continued to function fully even when it has been stretched more than 1,000% of its normal size.

Still hard to try to think about when this new technology will be available on consumer devices. Easier, however, to understand what might be the most interesting area of ​​application for these products. And that is one of the wearable that could really “turn” if equipped with soft and flexible displays.
