Flexible flash memory for wearable gadgets created

Создана гибкая флеш-память для носимых гаджетов Modern smartphone manufacturers consider the release of increasingly compact, durable, flexible gadgets one of the ways to further improve their products. Developers have made significant advances in the production of flexible displays. However, for the complete appearance and preservation of the technical parameters of smartphones, it is necessary to manufacture cases and \and technical parameters. As the main material for the new product, scientists took one of the most durable materials at the present stage – graphene. The unique physical and mechanical properties of graphene – high strength, small thickness, the ability of the material to withstand repeated bending and the ability to conduct electric current allowed us to make a unique flash memory in the laboratory. The researchers used graphene oxide, which is placed on the basis of pure titanium, which oxidizes upon contact with oxygen. Moreover, unique indicators were achieved that exceeded all previous technical capabilities of devices made on the basis of graphene oxide. The experimenters created a structure with a length of 50 nanometers and a thickness of 8 nanometers, which made it possible to record and read information using electrical pulses lasting about 5 nanoseconds. During the experiment, the developed memory cells were located on a flexible basis. During cyclic bending with a radius of 9 mm, the flash memory withstood up to 5 thousand cycles without loss of efficiency. The prospects for the development of flexible flash memory are constrained by the high cost of the material – graphene. At the moment, the development of flexible smartphones is actively using the development of bendable and even roll-up OLED displays and flexible batteries. The high cost of technology does not yet allow designers to use their original ideas for flexible mobile gadgets. Manufacturers offer smartphones that bend in two or even one place. However, in the laboratories of China and Samsung are actively working on creating practical flexible smartphones, the output of which users have been waiting for more than one year.
