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，我们不仅要确定化学成分，还要确定与人类敏感性相关的因素。因为味道和气味是由许多化学物质接收后的综合结果决定的。该结果的基本部分是敏感性信息。因此，用化学物质的仪器分析方法来再现味道和气味是很困难的，从工程学的角度来看，这并不容易。因此有必要对生物接收机制进行建模并提取其基本部分作为改变化学物质所具有的信息的机制。在本研究中，我们重点关注化学物质衍生的极性信息作为这样的基本机制。因此，控制电极的极性，并开发了用于传感器的变换器，其极大地反映了用作测量对象的化学物质的极性部分。此外，我们专注于化学物质界面的吸附。它反映化学物质所带来的味道和气味，受极性和表面吸附的影响很大。这种传感器传感器通过主动改变界面的状态并对其进行控制，使界面上的信息多元化，并可以提取所需的化学物质信息。本研究通过控制铂电极的界面电位，通过电化学表面阻抗的变化来测量界面上物质的状态。结果，可以高灵敏度地检测各种化学物质。事实证明，灵敏度的顺序与人体的化学感觉顺序相对应，测量得到的阻抗的电位分布图具有人体化学感官上化学物质质量的信息，电极表面处理也可以作为界面信息复用的手段。这些结果将来可以用作化学物质感性感知系统的传感器。较少的
