1.Olfactory SensorWe have developed the sensing system to the discriminate different gas species and also to evaluate their individual concentrations, based on the information embedded in nonlinear dynamical response of ceramic gas sensor. As a sensing system along this line, we have confirmed that the dynamic response with the application of periodic heating current can serve as the useful informational source. In the actual experiment on the analysis of gases, we have shown that our sensing system can discriminate the carbon number in various hydrocarbon, which has been almost impossible in the current technology of gas sensing. We have analyzed the nonlinear response with the aid of computer simulation, taking into consideration of kinetic effects such as absorption/desorption and oxidative reaction. From there results, it becomes apparent that our sensing system is suitable for various kinds of practical applications.2.Taste SensorIn order to develop the sensor to detect various chemical species in aqueous environment, we have tried to make stable sensing membrane on metal surface as the detector. It has become possible to evaluate the physico-chemical state at the metal surface by use of UV,FTIR and SEM.From such studies, it has become possible to construct stable chemical sensing membrane on several kinds of metal surface. These membranes are expected to be suitable for the future application towards the realization of taste sensation.

1.嗅觉传感器基于陶瓷气体传感器的非线性动力学响应信息，我们研制了一种用于识别不同气体种类并评估其个体浓度的传感系统。作为一个传感系统沿着这条线，我们已经证实，动态响应与应用程序的周期性加热电流可以作为有用的信息源。在实际的气体分析实验中，我们已经证明，我们的传感系统可以区分各种碳氢化合物中的碳数，这在目前的气体传感技术中几乎是不可能的。我们分析了非线性响应的计算机模拟的帮助下，考虑到动力学效应，如吸收/解吸和氧化反应。从这些结果来看，很明显，我们的传感系统适用于各种实际应用。2.味觉传感器为了开发传感器来检测水环境中的各种化学物种，我们尝试在金属表面上制备稳定的传感膜作为检测器。利用UV、FTIR和SEM等技术可以对金属表面的物理化学状态进行评价，从而为在多种金属表面构建稳定的化学传感膜提供了可能。这些膜有望适用于未来实现味觉的应用。
