\n<\/span><\/p>\nScottish researchers have helped to create a device which improves memory storage for technology including MP3s, smartphones and cameras.<\/p>\n
The device uses a tiny mechanical arm to translate data into electrical signals.<\/p>\n
This allows faster operation and uses less energy compared with conventional memory storage products.<\/p>\n
The Edinburgh University researchers worked with the Konkuk University and Seoul National University, in Korea.<\/p>\n
The device records data by measuring the current passing through a carbon nanotube, and the binary value of the data is determined by an electrode that controls the flow of current.<\/p>\n
Previous attempts to use carbon nanotube transistors for memory storage hit a stumbling block because they had low operational speed and short memory retention times.<\/p>\n
By using a mechanical arm to charge the electrode, which operates faster than conventional memory devices, scientists have been able to overcome the problems.<\/p>\n
‘Novel approach’<\/span><\/p>\nProf Eleanor Campbell, from Edinburgh University’s school of chemistry, said: “This is a novel approach to designing memory storage devices.<\/p>\n
“With this device you have much faster switching on and off which you do not have with conventional memory storage devices.<\/p>\n
“However, one of the issues with these novel devices is how easy they can be manufactured on an industrial scale, which we are yet to see.”<\/p>\n
Prof Campbell said research was continuing with colleagues in Korea on increasing the operating speed of the device even further.<\/p>\n
The findings were published in the journal Nature Communications.<\/p>\n<\/p><\/div>\n<\/p>\n
