A newly smell communication system with analyzing and reproducing chemical constituents of smell was investigated with three steps, (A) Constructions of biochemical gas-sensors and nose system with high gas-selectivity, (B) Fabrication of a smell regenerator, (C) Construction and sensory evaluation of the smell communication system. The detailed results are described as follows.(A) Several kinds of biochemical gas-sensors (bio-device, bio-sniffer) were developed by immobilizing biological catalysts (enzyme) onto sensing tip of dissolved oxygen electrode, screen printed electrodes and oxygen sensitive optical fibers. Detectable gas-substances: ethanol, dimethyl sulfide, trimethylamine, methyl mercaptan, ammonia, acetaldehyde, formaldehyde, etc.(B) The smell reproducer for typical smell constituents, ethanol (alcohol-), trimethylamine (fish-), methyl mercaptan (radish-) and dimethyl sulfide(seaweed-odor substance), was fabricated using 2 x 2ch gas-generators (totally 4ch).(C) The smell communication system for the above mentioned constituents was constructed by connecting (A) the bio-nose with (B) the gas-reproducer. The system was applied for smell communications of food and drink (alcohol, fish, radish and seaweed), and evaluated by the sensory test with healthy male subjects, thus obtained over 80% of smell transmissibility.

通过三个步骤研究了一种新的气味通信系统，并通过三个步骤研究了气味的化学成分，（a）具有高气形选择性的生化气体传感器和鼻子系统的结构，（b）闻到的造成气味，（b）构造的结构，（c）和气味通信系统的感官评估。 （a）通过将生物催化剂（酶）固定到溶解的氧气的传感尖端，筛选电极，丝网印刷电极和氧气敏感的电极通过将生物化学气体传感器（生物脱发，生物 - 刺）描述如下。光纤。可检测的气体溶质：乙醇，二甲基硫化物，三甲基胺，甲基胃胃，氨，氨，乙醛，甲醛，甲醛等。 - ）和二甲基硫化物（海藻二氧化物物质）是使用2 x 2ch气体发电机（完全4ch）制造的。（c）上述成分的气味通信系统是通过连接（a）与（a）与生物鼻子构建的（b）气体产生器。该系统用于食物和饮料（酒精，鱼类，萝卜和海藻）的气味通信，并通过感官测试对健康的男性受试者进行评估，因此获得了超过80％的气味传播性。
