项目摘要

When we measure taste and odor substances, we must decide not only the chemical composition but the factor relating human sensitivity. Because taste and odor are determined by the comprehensive results after many chemical substances were received. The basic part of this result is the sensitivity information. Therefore, it is difficult to reproduce taste and odor using instrumental analysis method for chemical substances, and from a engineering standpoint, it is not easy. So it is necessary to model on biotic reception mechanism and extract its basic parts as a mechanism to change the information which chemical sustances have.In the present research, we focused on the polar information derived from chemical substances as such a basic mechanism. Thus, the polarity of electrode was controlled and a transducer was developed for sensors which reflects greatly the portion about the polarity of chemical substances used as a measurement object. Moreover, we focused on adsorption to the interfa … More ce of chemical substances. It reflects taste and odor which are brought about by chemical substances are greatly influenced by the polarity and the adsorption to the surface. By changing the state of an interface positively and controlling it, such a transducer for sensors makes the information on an interface multiplex, and can extract required chemical substance information.In the present study, the interface potential of platinum electrode was controlled, and the state of the substance on an interface was measured through the electrochemical surface impedance change. As a result, various chemical substances could be detected with high sensitivity. And it turns out that the order of sensitivity corresponds to the chemosensory order of human, that the potential profile pattern of the impedance obtained by measurement has the information about the quality of chemical substances on the human chemical senses, and that an electrode surface treatment can also be used as a means to multiplex interface information. These results can be used as a transducer of the kansei sensign system of chemical substances in the future. Less

当我们测量味道和气味物质时，我们不仅必须决定化学成分，而且还必须决定与人类敏感性有关的因素。因为在收到许多化学物质后，味道和气味取决于综合结果。该结果的基本部分是灵敏度信息。因此，使用工具分析方法来重现味道和气味，从工程学的角度来看，这并不容易。因此，有必要建模生物接收机制，并提取其基本部分作为改变化学任务的信息的一种机制。在当前的研究中，我们专注于从化学物质中获得的极性信息作为这种基本机制。这是控制电极的极性，并为传感器开发了传感器，该传感器大大反映了用作测量对象的化学物质的极性。此外，我们将重点放在界面上的添加……更多的化学物质CE。它反映了化学物质带来的味道和气味，受到极性和表面添加吸收的影响很大。通过对接口的正面更改界面的状态并控制该界面，这种传感器的传感器可以使界面多路复用上的信息使所需的化学物质信息在本研究中提取所需的化学物质信息。在本研究中，控制了铂电极的界面电位，并通过电化学表面的障碍物测量界面上的物质状态。结果，可以高灵敏度检测到各种化学物质。事实证明，敏感性顺序与人类的化学感应顺序相对应，测量获得的阻抗的潜在特征模式具有有关人类化学感觉上化学物质质量的信息，并且电极表面处理也可以用作多重界面信息的手段。这些结果将来可以用作化学物质Kansei传感器系统的传感器。较少的
