摘要
传感器可以把化工、 土木、 机械和自然科学中的费电信号转变为电信号, 属于一种关键的换能器.从多个角度进行区分, 传感器有许多类型, 包括医学量、 生物参数、 声学量、 光学量、 热工量及几何机械量等.如果从输出信号进行区分, 可以将传感器分成电流、 电压、 数字信号和模拟信号 （脉冲波和连续波） 等.本文分析了传感器的发展历程、 具体应用、 发展趋势, 希望能为相关研究提供借鉴.
Sensors can convert electrical signals from chemical, civil, mechanical and natural science to electrical sig- nals, which is a key transducer. There are many types of sensors, including medical quantities, biological parameters, acoustic quantities, optical quantities, thermal quantities and geometric mechanical quantities. If the output signal is distinguished, it can be divided into types of current, voltage, digital signal and analog signal （pulse wave and continuous wave）. This paper analyzed the development process, specific application and development trend of sensors, hoped to provide reference for related research.
