4. Vibration and acceleration sensors

The principle is to measure the force to which a mass M, called "seismic mass", is subjected under the action of acceleration. The measuring range is generally expressed in g (gravitational acceleration).

The main types of accelerometer are :

  • piezoelectric accelerometers (figure 12 a, b, c, d);

  • piezoresistive accelerometers (figure 12 e, f, g): on these...
