"Chances are, you’ve seen a person using a powered exoskeleton – what you might think of as a sort of bionic suit – but only in the movies. In the 2013 movie “Elysium,” for example, Matt Damon’s character has an exoskeleton that makes his body stronger and faster than it would otherwise be. Simply described, they are devices that can be externally worn, resembling the skeleton of the body part they are attached to and able to provide support in many ways."
