传感器是一种信息检测、传输的器件,主要由传感、换能、检测等部分组成由它获得信息和传输信息,再配合电脑工作、得出结果。以前,传感器中的敏感材料是由各种电子元器件组成的。现在,生物技术使传感器得到发展,出现了生物传感器。利用生物体或材料的特殊功能与相应的物理、化学检测器件相结合,便组成了生物传感器。60年代末期,美国科学家首先研制成功了用葡萄糖氧化酶和测氧电极组成的第一个生物传感器,这种传感器

Sensor is a kind of information detection and transmission device. It mainly consists of sensor, transducer, detection and so on. It obtains the information and transmits the information, and then cooperates with the computer to get the result. In the past, sensitive materials in sensors were made up of a variety of electronic components. Biosensors have now emerged with biosensors. The use of biological or material special features and the corresponding physical and chemical detection devices combine to form a biosensor. In the late 1960s, American scientists first developed the first biosensor composed of glucose oxidase and oxygen-measuring electrodes. The sensor
