Engineers at Polytechnique Montréal have developed a revolutionary parachute system using kirigami-inspired cuts in plastic sheets, creating stable aerial descent devices that could transform humanitarian aid and space exploration. The breakthrough, published today in Nature, demonstrates how precise laser-cut patterns transform flat plastic sheets into functional parachutes without traditional sewing or assembly.

Ancient Art Meets Modern Engineering
The research team, led by professors David Mélançon and Frédérick Gosselin from Polytechnique Montréal’s Mechanical Engineering Department, turned to kirigami—the Japanese art of cutting and folding paper—to solve longstanding parachute design challenges. Unlike conventional parachutes requiring complex manufacturing with multiple fabric panels and suspension lines, the kirigami approach uses a single plastic sheet with a “closed-loop” cutting pattern that transforms during deployment.
“Kirigami modifies the mechanical properties of materials through strategic cuts and folds,” explains Mélançon. “While children use it to create paper snowflakes, we’ve applied these principles to create functional aerial devices.” The technique has previously been used in extensible electronics and medical devices, but never before for parachute systems. The research builds on growing interest in kirigami-inspired engineering that transforms flat materials into complex three-dimensional structures.
Revolutionary Performance Characteristics
Testing revealed remarkable stability advantages over traditional parachutes. “One advantage of this parachute is that it quickly stabilizes and doesn’t pitch, regardless of the release angle,” says Mélançon. “And unlike conventional parachutes, it follows a strict ballistic descent trajectory.” The design automatically forms an inverted bell shape when any weight is attached, creating consistent aerodynamic performance without the oscillation common in conventional parachutes.
The team conducted extensive validation through numerical simulations, wind-tunnel tests, laboratory drops, and outdoor drone deployments. Remarkably, the parachute maintains its performance characteristics even when scaled to different sizes. “The parachute’s behaviour doesn’t change even when the size of the device is augmented,” notes Gosselin. “This suggests that it could be scaled up for larger applications.” The single suspension line attachment and seamless construction eliminate deployment failures common in traditional parachute systems.
Practical Applications and Humanitarian Potential
The researchers identify humanitarian aid as the most immediate application, particularly for delivering water, food, and medicine to remote or disaster-stricken areas. “The parachute has a very low production cost,” emphasizes Mélançon. “We made these parachutes by laser cutting, but a simple die-cutting press would also do the trick.” This manufacturing simplicity could enable local production in regions with limited industrial infrastructure.
Beyond terrestrial applications, the technology shows promise for space exploration missions, particularly for Mars landings where atmospheric conditions challenge conventional parachute designs. The consistent ballistic trajectory could improve landing precision for scientific instruments and supplies. The approach also offers potential for commercial package delivery systems, especially in areas lacking landing infrastructure.
Future Development and Expanded Capabilities
The research team is already exploring advanced cutting patterns to create parachutes with enhanced capabilities. “We want to change the patterns to go even further: the parachutes could descend in a spiral, for example, or glide before dropping,” Mélançon reveals. Future designs might enable payload sorting during descent, with different parachutes following distinct trajectories based on their cargo.
This represents “a whole new design endeavor that opens up a multitude of possibilities,” according to the researchers. The work demonstrates how kirigami principles can transform simple materials into sophisticated mechanical systems. As development continues, the team anticipates creating specialized patterns for specific applications, potentially revolutionizing how we approach aerial delivery across multiple sectors.
