Abstract:An odor recorder is a system with the capability of reproducing smells as well as recording them in the same manner as that realized in VCR. It consists of sensor array with partially overlapping specificities, the algorithm for the mixture quantification and the olfactory display. MIMO (Multi-Input Multi-Output) feedback control algorithm is mainly used so that the pattern matching between the sensor-response pattern of the target odor and that of the reproduced smell can be achieved. The typical smell of the apple flavor was successfully reproduced using the 8 constituents. Moreover, the dynamically changing odor was also reproduced even under the disturbances such as changes of the temperature and the humidity. The work about the odor recorder for recent several years is reviewed here.
