This suit looks kind of like bike shorts, with some wires and small machines around the waist, and cables down the legs. When it's turned on, a person expends less energy when moving.

"Essentially, we've kind of recreated an artificial muscle on the outside of the human body that's working in parallel with the underlying biological muscle," explains lead researcher Conor Walsh, an engineering professor at Harvard.
The suit weighs about 11 pounds. The team's research, published Thursday in the journal Science, finds that a person wearing this suit expended 9.3 percent less energy walking and 4 percent less energy running, compared to wearing no suit.
That's the equivalent of shedding 16 pounds of weight while walking, or 12 pounds while running.
Walsh notes that the exosuit field is changing fast. In the future, he says, the best assist devices may not be exosuits at all, but rather technology implanted inside a person's body.
