Tongue (in cheek) magnetic control for the disabled from Georgiatech
A tiny magnet embedded in a tongue through piercing, implantation or adhesion has been shown by a Georgia Institute of Technology team of researchers to be capable of acting as a controller for the user to direct the operation of electromechanical devices such as wheelchairs. The Georgia Tech Bionics Lab describes their Tongue Drive System in an article published online. They have also published a paper in Science Translational Medicine.
