How tongue-piercings and sensors can help paralyzed people drive wheelchairs

A team at Georgia Tech has come up with an ingenious way to steer a wheelchair if you can’t move your limbs and torso: your tongue, featuring a magnetic titanium piercing full of sensors. Currently, the most common driving method for people with tetraplegia involves sucking on or blowing into a straw, but the researchers’ method — which basically turns the tongue into a joystick by having the sensors talk to a headset that controls the chair — is apparently just as accurate and much faster. Associate professor Maysam Ghovanloo hopes to commercialize the technology through his startup, Bionic Sciences.
