在人类进入信息社会的时代,获取各种现象的信息,已成为当今的重大课题,因而作为信息采集的传感器得到了迅速发展和广泛的应用.按其物理、化学特性,目前已有力敏、温敏、磁敏、湿敏、气敏、离子敏等六类的敏感器件.由于敏感器件及传感器具有把各种非电量转换成电信号并加以检测的功能,因此它是人类观察各种现象的有力工具.人们称各类传感器是“电五官”,即它不仅可以代替人类五官的作用,而且还可以感受到人类感觉不到的
In the era when human beings enter the information society, acquiring the information of all kinds of phenomena has become a major issue nowadays, and as a sensor of information collection, the sensor has been rapidly developed and widely used. According to its physical and chemical characteristics, Sensitive, magnetosensitive, hygroscopic, gas-sensitive, ion-sensitive and other six kinds of sensitive devices.As the sensitive devices and sensors have a variety of non-electric power into electrical signals and to detect the function, so it is human observation of various phenomena Powerful tool.People said that all kinds of sensors are “electric facial features”, that is, it can not only replace the human facial features, but also can feel the human can not feel
