| Abstract Scope |
Biological materials possess a remarkable ability to adapt. Inspired by bone’s ability to regulate mineral density in response to mechanical stress, we report a material system that triggers mineral deposition from electrolytes onto piezoelectric matrices upon mechanical loading resulting in increase in mechanical properties.
Our research demonstrates that minerals preferentially form near crack tips where stress is concentrated. This process effectively blunts the crack and mitigates damage, resulting in a 90% reduction in crack propagation speed. The material can also repair damages by preferential formation of minerals on damaged sites.
Furthermore, we have expanded the use environment of this mechanism by synthesizing liquid-infused porous piezoelectric scaffold. This approach yielded over a 3600% increase in modulus and a 3000% increase in energy dissipation after 12 million cycles.
These findings offer transformative strategies for developing resilient, sustainable materials with potential applications in medical implants, robotics, and infrastructure. |
