Wireless Device a Boon to Spinal-injury Patients

A wireless device promises to be a boon for those with severe spinal injuries as it is capable of operating as a computer or an electrically powered wheelchair.

The sensors track the location of a tiny magnet attached to the users' tongues. In earlier versions of the tongue drive system, the sensors were mounted on a headset worn by the user.

Major Breakthrough With the Sensor Technology
Orthopedic smart device promises to make post-surgical diagnosis and follow up procedures more precise and efficient, shows study.

'By moving the sensors inside the mouth, we have created a tongue drive system with increased mechanical stability and comfort that is nearly unnoticeable,' said Maysam Ghovanloo, associate professor of computer engineering at the Georgia Institute of Technology, the US.

The new device contains magnetic field sensors mounted on its four corners that detect movement of a tiny magnet attached to the tongue, according to a Georgia statement.
