Researchers have helped create a device to improve memory storage for technology including MP3s, smartphones and cameras.

The device uses a tiny mechanical arm that translates data into electrical signals that allows faster operation.  This uses less energy compared with the conventional memory storage products.

Researchers at the Edinburgh University teamed up with the Seoul National University and Konkuk University in Korea.

This new device records data by measuring the current passing through a carbon nanotube.  The binary value of the data is then determined by an electrode that controls the flow of current.

Previous attempts to use carbon nanotube failed as they had low operational speed and short memory retention times.  The use of a mechanical arm to charge the electrode operates faster than traditional memory devices which allow scientists to overcome the previous problems.
