How Accelerometers Work
压电加速度传感器（AC响应）B0B体育平台下载
在加速度下,地震传感器的质量causes a change in electrical charge in the piezo element, which can be read out as a charge Q that is proportional to the acceleration. Piezoelectric elements behave like a capacitor providing voltage at a set internal resistance. With an optional charge amplifier integrated in the sensor casing (IEPE interface), the output is converted into a voltage.
Piezoresistive Acceleration Sensors (DC Response)
Direct current acceleration sensors are also called piezoresistive acceleration sensors. A piezoresistive accelerometer is based on changes in electrical resistance in a strain gauge (part of the sensor’s seismic system). To compensate for temperature fluctuations, these sensors require an additional internal or external temperature compensation for their output. Modern piezoresistive sensors accomplish this using special integrated circuits for all forms of on-board signal conditioning as well as on-site temperature compensation. You can either use these sensors with conventional glued-on strain gauges or opt for microelectromechanical systems (MEMS) technology instead.
