Intelligent Odor and Taste Sensor System with Molecular Recognition Ability and Its Application

为了开发具有分子识别能力的智能气味和味觉传感器系统，制备了金属氧化物半导体（MOS）型、石英晶体微天平（QCM）型和表面等离子体共振（SPR）型3种化学传感器，并对其性能进行了研究。最后，对这些传感器系统的应用进行了讨论。（1）利用MOS型传感器阵列和气体浓缩器进行了香蕉等食品的新鲜度检测实验。因此，它被发现，该系统是有效的食品新鲜度检测。(2)It发现SPR味觉传感器结合MOS型气味传感器的传感器系统对于日本清酒的质量控制是有效的。（3）由四种不同类型的MOS传感器组成的传感器阵列和一台计算机对传感器输出进行分析，是一种有效的早期火灾探测系统。

In order to develop an intelligent odor and taste sensor system with molecular recognition ability three types of chemical sensors such as Metal-Oxide Semiconductor (MOS)-type, Quartz Crystal Microbalance (QCM)-type and Surface Plasmon Resonance (SPR)-type were fabricated and their properties were investigated. Furthermore, the application of these sensor systems were discussed. Consequently, the following results were obtained :(1)The experiment of the freshness detection of food such as banana was carried out using MOS-type sensor array with gas concentrator. Consequently, it was found that the system is effective for freshness detection of food.(2)It was found that sensor system of SPR taste sensor combined with MOS-type odor sensor is effective for quality control of Japanese sake.(3)The sensor system which consists an array of four different type MOS sensors and a computer acting for output analysis of sensors is effective for early fire detection.
