Briefings

Researchers at Osaka Research Institute of Industrial Science and Technology (ORIST) developed a flexible silicon material using etched microscopic spiral springs. This metamaterial responds to terahertz waves with tunable mechanical properties, enabling bendable and stretchable applications. The study was conducted in collaboration with the University of Osaka and Tohoku University.

Key points

• Researchers at ORIST, University of Osaka, and Tohoku University successfully etched microscopic spiral springs into silicon to create a flexible material.
• The material's response to terahertz waves can be mechanically tuned, allowing for bendable and stretchable applications.

Context

This research represents a significant advancement in metamaterials, as it transforms fragile silicon into a flexible material capable of tuning responses to terahertz waves through mechanical deformation.

Limitations

The evidence is limited to the development of the silicon material and its initial response to terahertz waves. Specific performance metrics, durability under repeated bending, or long-term stability data are not provided in the source.
