| Outline of Final Research Achievements |
We have been studying on practical application of strain imaging sheet for simple and low cost social infrastructure health monitoring technology. In this project, we have succeeded in forming a large area of A3 size of colloidal crystal thin film on PET plastic sheet. We also developed a technique to form a coating layer that protects opal thin films from UV irradiation damage. For a practical field use, a strain imaging technology of far field (from a distance of over 20 m) was demonstrated. On the other hand, using the conventional strain gauge as a reference, it was found that there is a linear relationship between the peak shift of strain imaging sheet and measured strain gauge.
