A soft robotic exosuit "could help athletes run faster and farther" than ever before, said George Dvorsky at Gizmodo. Researchers at Harvard have designed a lightweight, wearable device that instantly improves athletic performance. The textile-based design contains flexible wires that "perform the function of a second set of hip extensor muscles, applying force to the legs with each stride."
