众所周知,要开发新型传感器,除开发新原理外,在很大程度上是取决于新材料、新器件,也可以说传感器的开发是与不断地开发新的敏感材料和挖掘现有敏感材料的各种功能特性密切相联的。敏感材料的开发几乎涉及到材料科学的整个领域,从金属材料到高分子材料、半导体材料、陶瓷材料、玻璃等。从材料角度来看,可以说传感器的材料已从“结构材料”的时代开始转向“功能材料”的时代了。下面介绍有关传感器的功能材料。 1.陶瓷材料天然陶瓷因其硬、脆、难于加工,吸收 As we all know, to develop new sensors, in addition to the development of new principles, depends largely on new materials, new devices, it can be said that the development of sensors is and continue to develop new sensitive materials and mining existing sensitive materials The kinds of features are closely linked. The development of sensitive materials involves almost the entire field of material science, from metal materials to polymer materials, semiconductor materials, ceramic materials, glass and the like. From the material point of view, it can be said that the sensor material has been from the “structural material” era began to “functional materials” era. The following describes the functional material of the sensor. 1. Ceramic Materials Natural ceramics because of its hard, brittle, difficult to process, absorb
