Exoskeleton Helps the Paralysed Walk

Exoskeletons frequently hit the news as projects to make super-soldiers, but a new, more slimline version has bee built by Israeli company Argo Medical Technologies. Inspired by the paralysis of one of their own engineers, ReWalk allows wearers to walk, use stairs, stand and sit.The wearer switches between "modes" with a tap on a wrist-pad, then controls the actual motion by shifting their upper body-weight. For instance, they would hit "stand", then lean forward to make the ReWalk straighten its exo-legs. The device is much more streamlined than some other systems, run from a very flat pack-pack, and can be worn all day, but is only suitable for paralysis victims who still have good control of their arms and shoulders.ReWalk seems much simpler and lighter than other exoskeletons, but that seems to be because the designers have not tried to replace the entire walking function - balance is still down to the wearer, using crutches, but I imagine practice could reduce that to sticks, or even a single stick.Weight and fitness seem to be factors as well - the man in the video is was an Israeli paratrooper, injured on duty, and there are no shots of the rather portly wheel-chair-bound inventor wearing the ReWalk, but I think you'll agree it would still be a major benefit to an awful lot of people.This video is in German, but shows more shots of the exoskeleton, and has clips of the designer discussing his project.

Bite force transducer embedded in a gumshield

I am a quadriplegic and paralysed from the shoulders down. I am working on a project to allow me to control a go kart. I have limited use of my arms which should allow me to control the steering but I am trying to get another degree of freedom to control acceleration and/or braking One of the ideas is to use a piezoelectric type force transducer in the mouth to control and acceleration via an arduino or similar. The transducer would detect bite force and it would be converted into control signals for the throttle and/or brake. It would be embedded in a gumshield and it would be acceptable to have a cable coming from the front of it to the control System. I am wondering has anyone worked on such a project and could anyone point me in the right direction please. The gumshield may end up looking something like the image here.
