In 2016, an inflatable arch wreaked havoc at the Tour de France bicycle race when it deflated and collapsed on a cyclist, throwing him from his bike and delaying the race while officials scrambled to clear the debris from the road. Officials blamed a passing spectator’s wayward belt buckle for the arch’s collapse, but the real culprit was physics.<\/p>\n

Today’s inflatable structures, used for everything from field hospitals to sporting complexes, are monostable, meaning they need a constant input of pressure in order to maintain their inflated state. Lose that pressure and the structure returns to its only stable form\u2014flat.<\/p>\n

But what if these structures had more than one stable state? What if the arch was just as stable inflated as it is flat on the ground?<\/p>\n

Now, researchers at the Harvard John A. Paulson School of Engineering and App<\/a>lied Science<\/a>s (SEAS) have developed bistable inflatable structures inspired by origami.<\/p>\n

The research is published in Nature<\/i>.<\/p>\n

“This research provides a direct pathway for a new generation of robust, large-scale inflatable systems that lock in place after deployment and don’t require continuous pressure,” said Katia Bertoldi, the William and Ami Kuan Danoff Professor of Applied Mechanics at SEAS and senior author of the paper.<\/p>\n

Inspired by origami and guided by geometry, the research team developed a library of triangular building blocks that can pop up or fold flat and be combined in different configurations to build closed, multistable shapes.<\/p>\n
