How Accelerometers Work
Piezoelectric Acceleration Sensors (AC Response)
Under acceleration, the seismic mass of the sensor 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.
Capacitive Acceleration Sensors (DC Response)
Capacitive acceleration sensors are based on changes in the electrical capacity of the seismic mass under acceleration. This is a widespread technology commonly used applications such as airbags and mobile devices. Our capacitive acceleration sensors are manufactured using microelectromechanical systems (MEMS) technology. Our high-end silicon MEMS accelerometers in instrumentation quality are resistant against prestress and produce very little noise.
