　　在基础学科研究中，传感器更具有突出的地位。现代科学技术的发展，进入了许多新领域：例如在宏观上要观察上千光年的茫茫宇宙，微观上要观察小到fm的粒子世界，纵向上要观察长达数十万年的天体演化，短到s的瞬间反应。此外，还出现了对深化物质认识、开拓新能源、新材料等具有重要作用的各种极端技术研究，如超高温、超低温、超高压、超高真空、超强磁场、超弱磁场等等。显然，要获取大量人类感官无法直接获取的信息，没有相适应的传感器是不可能的。许多基础科学研究的障碍，首先就在于对象信息的获取存在困难，而一些新机理和高灵敏度的检测传感器的出现，往往会导致该领域内的突破。一些传感器的发展，往往是一些边缘学科开发的先驱。

　　伺服电机(servomotor)是指在伺服系统中控制机械元件运转的发动机，是一种补助马达间接变速装置。伺服电机可使控制速度，位置精度非常准确，可以将电压信号转化为转矩和转速以驱动控制对象。伺服电机转子转速受输入信号控制，并能快速反应，在自动控制系统中，用作执行元件，且具有机电时间常数小、线性度高、始动电压等特性，可把所收到的电信号转换成电动机轴上的角位移或角速度输出。分为直流和交流伺服电动机两大类，其主要特点是，当信号电压为零时无自转现象，转速随着转矩的增加而匀速下降。
