固态压阻传感器是一种新型的现代传感器。它是利用半导体材料压阻效应特别显著的特点,在半导体基片上用集成电路工艺制成的四只扩散电阻(或同时做成某些测量电路),直接做为测量传感元件,并接成平衡电桥,在压力作用下,各电阻值发生变化,破坏了电桥平衡,输出相应的电压,测得电桥输出电压,即可得到压力值,主要用了测量力、压力、加速度等。
Solid state piezoresistive sensor is a new type of modern sensor. It is the use of semiconductor materials, piezoresistive effect is particularly significant feature of the semiconductor substrate with integrated circuit technology made of four diffusion resistance (or made of some measurement circuit at the same time), as a direct measurement of sensing components, and then connected Balanced bridge, under pressure, the resistance value changes, undermining the balance of the bridge, the output voltage, measured bridge output voltage, you can get the pressure value, the main use of measuring force, pressure, acceleration and so on.
