气味检测在食品安全控制、环境检测、缉毒、炸药搜索等社会安全防范方面起到重要作用。哺乳动物具有异常高灵敏的嗅觉系统,能检测到空气中极其痕量的气体分子,在缉毒、搜爆、反恐等社会防范方面发挥着重要的作用。本课题组提出了一种新型的基于植入式脑机接口的在体生物电子鼻:利用哺乳动物的嗅上皮作为初级气味感受器,气味信息通过嗅球和嗅皮层修饰处理后,将植入式微电极阵列包埋于嗅球或嗅皮层记录其响应信号,通过对记录到的神经元信号进行分析解码,实现气味检测与识别。本文重点介绍了在体生物电子鼻的原理、组成结构、技术实现、应用等,最后,对该领域的发展趋势进行了展望。
Odor testing plays an important role in social safety precautions such as food safety control, environmental testing, anti-drug and explosives search. Mammals have an abnormally sensitive olfactory system that can detect extremely trace amounts of gas molecules in the air and play an important role in social protection such as drug trafficking, explosion detection and anti-terrorism. Our group proposed a novel bioelectronic nose based on implantable brain-computer interface: using the mammalian olfactory epithelium as the primary odor sensor, the odor information was modified by the olfactory bulb and the entorhinal cortex, and the implantable microelectrode The array is embedded in the olfactory bulb or the entorhinal cortex to record its response signal. The recorded neuronal signals are analyzed and decoded to realize odor detection and recognition. This article focuses on the principle, compositional structure, technical realization and application of in vivo biological electronic nose. Finally, the development trend of this field is prospected.
