A team of engineers from Polytechnique Montréal report a new and unique parachute concept inspired by the Japanese art of kirigami today in Nature. This simple, robust and low-cost approach has a wide variety of potential applications ranging from humanitarian aid to space exploration.

Kirigami is a technique that modifies the mechanical properties of a sheet of material by making precise folds and cuts to it. Children use it to make snowflakes out of paper, and engineers have used it to create extensible structures, flexible medical devices and deployable spatial structures. However, kirigami techniques have never been applied to parachute production.

The Polytechnique Montréal research team has now changed all that.
