Auxetic metamaterials for hybrid hip-joint implants

Overview

Auxetic metamaterials offer a groundbreaking solution for hip-joint implants, utilizing their unique property of a negative Poisson ratio. This means they contract laterally under tension, preventing expansion that can harm surrounding bone tissue. By incorporating these materials into hip-joint implants, we aim to improve mechanical behavior and significantly reduce the risk of infection, offering a safer and more effective alternative for patients requiring joint replacement surgery.

Technical specifications

• Negative Poisson Ratio: Ensures lateral contraction under tension, minimizing damage to bone tissue.
• Hybrid Distribution: Optimized auxetic geometries tailored for hip-joint applications.
• 3D Printing Capability: Employs advanced 3D printing techniques with titanium-based materials for durable and biocompatible implants.
• Collaborative Design: Developed in collaboration with medical schools, leveraging extensive research and expertise.

Technology readiness level

Currently at TRL 2, this technology is in the early stages of development. Initial designs have been conceptualized, and validation through further design and testing is planned. Collaboration with medical institutions and regulatory bodies is essential to advance this technology towards commercial viability.
