Outline of Final Research Achievements

Reliable degradation diagnosis is essential to maintain constructions. To address this issue, more advanced inspection and diagnosis techniques that are less costly and easier to operate and yet highly reliable and efficient should be developed. Applying visualization materials is focused as one of the most promising methodologies for the health monitoring technologies. We developed luminescent strain visualization sheet material by dye impregnation into an existing artificial opal film.
