| 中文摘要 | for an olfactory sensor or electronic nose, the task is not only to detect the object concentration, but also to recognize it. it is well known that all the elements can be identified by their charge to mass ratio e(+)/m. we tried to imitate this principle for molecular recognition. two kinds of sensors are used simultaneously in testing. one is quartz crystal microbalance (qcm) for detecting the change in mass, the other is interdigital electrode (ie) for detecting the change in conduction, as an electro-mass multi-sensor (emms). in this paper, the principle and the feasibility of this method are discussed. the preliminary results on the recognition of alcohol by emms coated with lipids are presented. meanwhile, the multi-sensor can also be used as an instrument for research on some physico-chemistry problems. the change in conduction of coated membrane caused by one absorbed molecule is reported. it is found that when a qcm is coated with membrane, it still obeys the relationship delta f (frequency change of qcm) = k delta m (mass change of absorbed substance) and the proportional coefficient, k, depends not only on quartz properties but also on membrane characteristics as well.
