| Research Abstract |
The present study develops the smell sensor by using the color change by the solvent polarity of the dye molecule. The coloring matter was spread on the optical fiber and a simple device was developed by the change in the light intensity. Moreover, the pilot machine was improved at the same time for the improvement of sensitivity, and the response and the multivariate analysis in a standard smell were done. It experimented by using the smell elements of two kinds of coloring matters (Alizarin Yellow, Phenol Pthalein) and alcohol and standard smells, etc. It was thought that the difference of the pattern of the amount of the change and the response was clear by the smell element. To express numerically and to compare this difference, the principal component analysis on the multivariate analysis was done.
