Abstract

This study aims to evaluate the deformation and damage of cement composites using a dynamic discoloration sensor that changes color when mechanical and physical stresses are applied. The sensor operates without power and can monitor the status of a structure in real-time, reducing the need for various factors required for a structural health assessment. The experimental results showed that the sensor changes color in response to the deformation of the specimen and can monitor the crack propagation in real-time. The sensor also recognizes the color change in the freeze-thaw environment. However, to improve the accuracy of monitoring, it is necessary to improve the reliability of the model and the experimental environment based on data collected under various conditions, such as the attachment location and surface of the sensor.
