A team of researchers at Queen’s University in Canada has developed an exoskeleton that reduces the metabolic cost of walking. In their paper published in the journal Science, the group describes their system and how it works. Raziel Riemer, Richard Nuckols and Gregory Sawicki with the Ben-Gurion University of the Negev, Harvard University and the University of Georgia, respectively, have published a Perspectives piece in the same journal issue outlining the work by the team.
