Applied origami. Using origami design principles to fold reprogrammable mechanical metamaterials

Area of Science:

• Materials Science
• Mechanical Engineering
• Physics

Background:

• Origami, the art of paper folding, is increasingly recognized for its potential in mechanical metamaterial design.
• The Miura-ori tessellation, a specific origami pattern, exhibits unique mechanical properties.

Purpose of the Study:

• To explore the mechanical properties of the Miura-ori tessellation for metamaterial applications.
• To demonstrate the tunability of mechanical properties through origami principles.
• To establish a link between origami, mechanical metamaterials, and programmable matter.

Main Methods:

• Investigated the mechanical bistability of individual Miura-ori unit cells.
• Analyzed the emergent crystallographic structures formed by interacting unit cells.
• Explored the scale-free nature of origami for diverse applications.

Main Results:

• Each Miura-ori unit cell is mechanically bistable, allowing reversible tuning of compressive modulus.
• Interactions between unit cells lead to emergent crystallographic structures like vacancies and dislocations.
• Origami-based metamaterial design is applicable across multiple length scales (milli-, micro-, and nanometer).

Conclusions:

• Origami provides a versatile framework for designing tunable mechanical metamaterials.
• The principles of origami enable the creation of programmable matter with emergent properties.
• This approach offers a scalable pathway for advanced material design.
