We aimed to establish the fundamental stage of recording and reproducing olfactory information using an odor sensing system. The communication with five senses might become more feasible if the technology for recording and reproducing smells is established and is implemented into a multimedia.The experiment on recording and reproducing the smells of the apple and citrus flavors was performed. The sensory test revealed that the smell reproduced by our developed system was identical to the target apple flavor. Then, real-time reference method, which alternately switches the target and blended odors at the interval of several seconds, was implemented into the odor recorder. It contributed to the enhancement of the robustness against the environmental change such as temperature and humidity changes. Moreover, it was found that the dynamical change of the odor recipe could be recorded even under the environmental change using the real-time reference method. The odor recipe change over 5 sec … More onds could be captured when we simultaneously used the two same sensor arrays.Then, the concept of the odor approximation was introduced to reduce the number of the component odors. We also made the system for blending up to 96 component odors using an auto sampler. We tried to approximate apple, banana, orange and melon flavors made up of 10-20 component odors using 3 component odors, respectively. The human sensory test revealed that the odors with similar locations on the scattering diagram of Principal Component Analysis were close. In addition, the perfumes with various recipes of base notes were measured. Since the sensor responses to the automatically blended odor was close to those to the manually blended one, it was found that the sufficient accuracy was obtained using the auto sampler. We will do the large-scale experiment from now on and expect that these two methods such as odor approximation and the auto sampler will drastically expand the range of odor for the odor recorder.Finally, the odor blender composed of inkjet devices and the mesh heater was realized to solve the problem of the slow speed for the movement of low-volatile odor. The odor was rapidly generated and vanished using the proposed odor blender. The binary recipe of jasmine flavor was obtained using this odor blender and the gradient descent method. Less

我们的目标是建立使用气味传感系统记录和再现嗅觉信息的基础阶段。如果建立气味的记录和再现技术并将其应用于多媒体中，则五官交流将变得更加可行。感官测试表明，我们开发的系统再现的气味是相同的目标苹果风味。然后，实时参考方法，交替切换目标和混合气味在几秒钟的时间间隔，被实施到气味记录器。这有助于增强对环境变化（如温度和湿度变化）的鲁棒性。此外，它被发现，即使在环境变化的气味配方的动态变化，可以记录使用实时参考方法。气味配方在5秒内发生变化 ...更多信息 同时使用两个相同的传感器阵列，可以捕获气味。然后，气味近似的概念，以减少组分气味的数量。我们还使用自动采样器混合了多达96种成分的气味。我们尝试分别使用3种组分气味来近似由10-20种组分气味组成的苹果、香蕉、橙子和甜瓜风味。人体感官实验表明，在主成分分析的散射图上位置相近的气味接近。此外，测量了具有各种基香配方的香料。由于传感器对自动混合气味的响应接近于对手动混合气味的响应，因此发现使用自动采样器获得了足够的准确度。接下来我们将进行大规模的实验，期望气味近似和自动进样器这两种方法能极大地扩展气味记录仪的气味范围。最后，我们实现了由喷墨装置和网状加热器组成的气味混合器，解决了低挥发性气味移动速度慢的问题。使用所提出的气味混合器，气味迅速产生并消失。利用该气味混合器和梯度下降法得到了茉莉香精的二元配方。少
