Scalable Elasticoluminescent Strain Sensor for Precise Dynamic Stress Imaging and Onsite Infrastructure Diagnosis

Abstract Precise dynamic stress/strain imaging is critical for a broad range of research and engineering analyses ranging from micrometer to meter‐scales, but there is no precise multiscale strain sensor, especially for onsite real‐time structural health monitoring. Here, a scalable elasticoluminescent strain sensor is presented for solving worldwide structural diagnosis problems ranging from micrometer to meter‐scales. Significant progress has recently been made on both highly sensitive elasticoluminescent sensors and quantitative evaluations in dynamic stress/strain imaging. The precise dynamic imaging of stress/strain and onsite fracture inspection and danger‐level (stress concentration) diagnoses on large‐scale infrastructures are demonstrated. The innovative scalable strain sensor would prospectively open a new era in multiscale strain imaging research and contribute to multifield research related precise dynamic stress/strain imaging and healthcare of structures.
