摘　　要：介绍了一种基于LB膜的集成味觉图像传感器的原理、制作过程及其在味觉物质检测中的应用。传感器由多种不同特性的类脂薄膜组成 ,采用LB(Langmuir -Blodgett)膜 (单分子复合膜 )技术沉积到LAPS系统上 ,能以近似人体味觉方式检测味道。实验测试了传感器对甜、酸、苦、咸、鲜 5种基本味觉物质溶液的响应 ,进行了响应图像的处理和模式识别 ,达到了对不同味觉物质的区分、检测。The principle, the manufacture and it's application in the detection of taste substances of the taste image sensor based on LB (Langmuir-Bleodgett) films were introduced in this paper .The sensor were composed of lipid membranes with different characteristics and the membranes were deposited on the LAPS system by LB method.As a result, the taste can be detected like human being. In the experimental study, the response potential of five kinds of basic taste substances were measured by taste image sensor in to get different response potential images. Besides, the image processing and pattern recognition were also carried out to detect different taste substances.
