Breakthrough 3D Helical Metamaterial Achieves Zero Poisson’s Ratio Under Large Strain

A novel 3D helical metamaterial demonstrates exceptional zero Poisson’s ratio characteristics while maintaining dimensional stability under large strains. The breakthrough design shows promise for applications in shape-morphing structures and smart actuators, according to recent research findings.

Revolutionary 3D Metamaterial Defies Conventional Mechanical Behavior

Researchers have developed an innovative three-dimensional helical metamaterial that maintains zero Poisson’s ratio (ZPR) characteristics even under substantial strain conditions, according to recent reports in Communications Materials. The breakthrough design reportedly overcomes limitations of previous metamaterials by combining the compliance and ZPR properties of Fish Cells with improved geometric configuration using optimized helical structures.
