电子鼻又称气味扫描仪,是一种智能仿生传感器系统,是电子感觉传感器中开发应用最广泛的一种,可以嗅出各种气味甚至从多种混合气体中的定性或定量地检测到某种气体。人体的嗅觉系统是一种特殊的化学敏感器官,有着相当出色的性能,可对自然界上千种气味做出反应。过去的十几年中,人们对嗅觉过程的理解迅速增加,并试图建立过程模型。目前有关嗅觉的解释超过了30余种,但尚未有一种理论能完全清楚地解释确切的细节。趋于一致的观点是,嗅觉是物质气味分子的识别过程:气味分子通过鼻腔到达神经元,初级神经元的轴突再把感受到的信息传达到嗅球(由数万个初级神经元汇聚而成的二级神经元)。初级嗅觉神经元的信息在这里进行调节
Electronic nose, also known as odor scanner, is a kind of intelligent biomimetic sensor system. It is the most developed and applied electronic sensory sensor. It can detect various odors and even detect qualitatively or quantitatively from a variety of mixed gases. Kind of gas The human olfactory system is a special type of chemical-sensitive organ that has very good properties and responds to thousands of scents in nature. Over the past decade or so, people’s understanding of the olfactory process has rapidly increased and attempts have been made to establish process models. At present, there are more than 30 kinds of explanations about the sense of smell, but no theory can explain the exact details completely and clearly. The consensus point is that smell is the process of identifying molecules of matter: the molecules of the odor reach the neurons through the nasal passages, and the axons of the primary neurons then transmit the sensed information to the olfactory bulb (a collection of tens of thousands of primary neurons Secondary neurons). Primary olfactory neuronal information is regulated here
