The Problem
Concrete infrastructure like bridges and buildings develop small cracks over time because of factors like stress, weather, or aging. These cracks are often not noticed until they become serious, which leads to expensive repairs or structural failure. Current monitoring systems are inefficient in detecting damage and is also not able to repair it, so structures continue to weaken.
Future Work

In the future, this technology could transform infrastructure by combining early damage detection with automated repair into a single system that allows structures to maintain themselves over time. Continued advancements in materials, nanotechnology, and sensor networks would make it possible to improve nanoparticle delivery, and develop more reliable materials that form C-S-H gel, and refine ultrasonic guidance in porous concrete.

The Innovation
ReACT-SHM proposes a responsive structural health monitoring system that integrates embedded sensing, damage localization, and autonomous self-repair within concrete infrastructure. Unlike current monitoring systems that only detect structural damage, this system uses sensors, including Fiber Bragg Grating sensors and acoustic emission sensor data, to trigger the release and ultrasonic guidance of self-healing nanoparticles toward crack locations.
