Accelerometers are mechanical/electronic vibration sensors for the detection and measurement of vibration, inclination and acceleration. They are installed in components, devices, plants and systems and can record measured values

in all three axis directions. Accelerometers are inertial sensors

. They use the change in inertial force, which is determined by the earth's gravitational force of 9.81 m/s atrest. Depending on the method, the changes in motion can be detected by piezoceramics using the piezoelectric effect

or capacitively by changes in charge. In both methods, a charge change is produced that corresponds to the applied force change. Acceleration sensors are used in a wide variety of biological, medical and technical fields and can detect the smallest displacements of buildings or dams, as well as extremely rapid changes in automotive and rocket technology. A well-known example of acceleration sensors is the smartphone, which adjusts the screen display when the position changes.
