要約(日本語): Our odor recorder is able to record the target odor as the recipe of several odor components. It is based on an array of quartz crystal microbalance (QCM) odor sensors coated with sensing films. With a system enabling to obtain both the resonant frequency shifts and resistance changes from a QCM, the selectivity of the sensor array has been improved. To the best of our knowledge, this is the first paper about using resistance changes in QCM based odor recorder. Herein, an improved control algorithm is also proposed. Odor mixture quantification experiment results indicated that odor recorder with the proposed control method using both frequency shifts and resistance changes improved the quantification accuracy and convergence time.
