Researchers at McGill University have unveiled a new development in shape-shifting materials inspired by kirigami—the Japanese art of paper cutting. This innovation has the potential to revolutionize various design fields, from architecture and product design to fashion and packaging. These adaptable materials can morph into different shapes while retaining their structural integrity, presenting opportunities for creative applications across a wide range of disciplines.

The Science Behind the Material
The innovation leverages kirigami-inspired geometric patterns, where precise cuts enable materials to transform dynamically. The research focuses on “anisotropic morphing,” where structures expand or contract differently depending on the direction of force applied. For example, a square can morph into shapes like a rectangle or trapezoid, making these materials highly versatile. Unlike conventional materials, these engineered solutions exhibit multi-functionality and adaptability, opening up new possibilities for sustainable design and functional applications.

Applications in Design
This advancement has significant implications for architecture and interior design, where adaptive materials can be used for dynamic facades, shading systems, or modular interiors that adjust to environmental conditions such as light, temperature, or user needs. These innovations could lead to more energy-efficient and customizable spaces. In product design, furniture or accessories that transform to meet different needs could reduce the requirement for multiple products, promoting a more sustainable, circular design ethos. In fashion and wearable technology, shape-shifting materials could pave the way for garments or accessories that adjust to body movements or environmental conditions, blending functionality with aesthetics. For packaging design, these materials can enable packaging that morphs to fit different product sizes, reducing material waste and improving efficiency in distribution. In automotive design, dynamic materials could enhance vehicle aerodynamics or provide adaptable interiors, contributing to better energy efficiency and user comfort.

Sustainability and Circularity
A key advantage of these materials is their potential for sustainability. Their adaptability reduces the need for multiple, single-use products, aligning with principles of circularity. Although the current research focuses on the engineering of these materials, future iterations could integrate bio-based or recycled components, further enhancing their environmental impact.

What’s Next?
The researchers, led by Professor Damiano Pasini of McGill’s Department of Mechanical Engineering, have already filed patents for this technology. While the primary focus has been on understanding the mechanics of shape transformation, future efforts will likely explore practical applications tailored to industry needs. This is an exciting development for designers looking to push boundaries with innovative, adaptable materials.

About the Research
The study, titled “Anisotropic morphing in bistable kirigami through symmetry breaking and geometric frustration,” was published in Advanced Materials. It was funded by the Canada Research Chairs Program, the Natural Sciences and Engineering Research Council of Canada, and other international organizations.
