Say the term ‘power suit’ and most people think of bold corporate attire. But the expression takes on new meaning when it refers to a powered “exoskeleton,” like Ellen Ripley’s power loader in “Aliens,” or Iron Man’s armor from the Marvel films and comic books.
Until a few years ago, such exoskeletons — metal frameworks fitted with motorized “muscles” that can multiply the wearers’ strength far beyond that of normal humans — were entirely fictional. The only real-world exoskeletons were the natural external coverings of animals such as beetles and crabs; protective outer structures that provide a stiff frame upon which their muscles can push against to move their bodies around.
