A research team working in Germany and Korea have developed a lower-limb 

exoskeleton system that uses electoencephalogram (EEG) technology to transfer brain

waves into motion control commands. 

 

This is an important innovation because it can allow for people who can no longer use

their lower limbs to be able to move around without a wheelchair. For example, the

army veteran (in the picture) who was paralyzed from the waist down can walk again

using the $77,000 exoskeleton.

 

The machinery is around 50 pounds.
