Suppression of background odor effect in odor sensing system using olfactory adaptation model

摘要

In this study, a new method for suppressing background odor effect is proposed. Since odor sensors response to background odors with a target odor, it is difficult to detect the target odor information. In the conventional odor sensing systems, the effect of the background odors are compensated by subtracting the response to the background odors (the baseline response). Although this simple subtraction method is effective for constant background odors, it fails in the compensation for time-varying background odors. The proposed method for the background suppression is effective even for the time-varying background odors.
