Euler Spiral Flexure-Based Metamaterial Design ID: 2019-036

A revolutionary metamaterial design utilizing Euler spiral flexures to achieve unprecedented compactability and customizable mechanical properties.

Technology Overview

This invention introduces a new class of metamaterials designed using Euler spiral flexures (ESFs) to form base units of two mirrored planar four-bar compliant mechanisms. These mechanisms enable the creation of materials with unique characteristics such as high compactability, decoupled motion and stiffness, and a tailorable Poisson's ratio. By configuring the base units in various arrangements, it is possible to fabricate materials that can be compressed into hyper-compact states for storage and arranged into three-dimensional architectures to achieve desired mechanical properties by adjusting their geometric parameters.

Key Advantages

• High compactability allowing for hyper-compact storage
• Customizable mechanical properties including decoupled motion, stiffness, and a tailorable Poisson's ratio
• Capability to achieve unique configurations and mechanical properties by varying the orientation and placement of base units
• Superior to existing metamaterials with added benefit of full compressibility

Problems Addressed

• Limitations in compactability and mechanical customizability of current metamaterial designs
• Inability to achieve decoupled motion and stiffness in conventional materials
• Challenges in tailoring Poisson's ratio for specific applications

Market Applications

• Industries requiring materials with high compactness and significant motion capabilities
• Applications demanding customizable mechanical properties for specialized use cases
• Potential for advancements in material science, robotics, aerospace, and more through unique material configurations
