Versatile Sacrificial Mold-Assisted 3D Printing for High-Performance Mechanoluminescent Structures Toward Impact Protection and Visualization Monitoring.
Mechanoluminescence (ML) materials exhibit significant potential for visual sensing and structural monitoring owing to their self-powered operation and capability for real-time stress mapping. However, the fabrication of complex and high-aspect-ratio 3D ML geometries remains challenging, primarily constrained by poor r...
