Novel sensors to measure various liquid properties have been developed to realize a total system for evaluating a taste and smell of a beverage. An interdigital electrode sensor has been developed to measure the conductivity and the dielectric constant of liquid. Since their frequency dispersions depend on ions and specific molecules in liquid, information on taste can be obtained from them. Moreover, nonelectrolytes, such as sugar, can be detected using electrodes coated with an organic molecular film.Sueface acoustic wave (SAW) sensors have been used to measure the viscosity and the density of liquid since they are closely related to feeling of texture. A new method to measure them independently has been proposed at first using two saw devices, i.e., a SH=SAW device and a SV=SAW one. A small integrated sensor has then been realized, which can excite both SAWs on the same substrate.A smell of liquid is also an important factor to determine the total impression of a beverage. Quartz cr … More ystal microbalance (QCM) sencers have been used to detect it, and a mixture composition of liquid is successfully identified by the active sensing method.The key part to develop an excellent chemical sensor is a sensing film. Therefore, the oscillation circuit behavior of a QCM sensor has been studied so that the film condition suitable for detecting a resonance frequency shift was determined. Sensing film characterization for a QCM sensor has then been done to classify the films systematically. Moreover, it has been found that the sensitivity and the selectivity of a sensor are largely influenced not only by the material of the film but also by its structure. Therefore, a new method to fabricate a film with high selectivity has been proposed. The shape of the target molecule is imprinted onto a self-assembly film of organic material, and the experimental results show the excellent selectivity of this film. It is expected that a total system for beverage evaluation can be realized by integrating all the sensors developed in this study. Less

用于测量各种液体性质的新型传感器已被开发出来，以实现一个评估饮料味道和气味的整体系统。研制了一种用于测量液体电导率和介电常数的双数字电极传感器。由于它们的频率分散取决于液体中的离子和特定分子，因此可以从中获得有关味道的信息。此外，非电解质，如糖，可以使用涂有有机分子膜的电极来检测。由于液体的粘度和密度与质地感密切相关，表面声波传感器已被用于测量液体的粘度和密度。首先提出了一种利用两种锯切装置，即SH= saw装置和SV= saw装置独立测量它们的新方法。然后实现了一个小型集成传感器，它可以在同一衬底上激发两个saw。液体的气味也是决定饮料总体印象的一个重要因素。利用晶体微天平（QCM）传感器对其进行了检测，并通过主动传感方法成功地鉴定了混合液体的组成。传感膜是研制优良化学传感器的关键。因此，研究了QCM传感器的振荡电路行为，确定了适于检测谐振频移的薄膜条件。然后对QCM传感器的传感膜特性进行了系统的分类。此外，还发现传感器的灵敏度和选择性不仅受薄膜材料的影响，而且受其结构的影响。因此，提出了一种制备高选择性薄膜的新方法。将目标分子的形状印迹在有机材料的自组装膜上，实验结果表明该膜具有优异的选择性。期望将本研究开发的所有传感器整合在一起，可以实现一个完整的饮料评价系统。少
