2022/7/21 · The piezoelectric material slice, often a ferroelectric ceramic that has been artificially polarized, is what gives piezoelectric accelerometers their distinctive piezoelectric effect. It produces an electrical charge across its pole faces in response to mechanical stress, whether it be in tension, compression, or shear, and this charge is proportional to the applied force.

of vibration sensors compared to piezoelectric accelerometers: Sensor Type The sensing element of a piezoelectric accelerometer consists of two basic.

Piezoelectric type accelerometers were the first commercial one sold. In this diagram, the piezoelectric crystal is sandwiched between the proof mass and 

ADXL345 is a 3-axis capacitive accelerometer with 13 bits resolution and low power. Can measure between ±2g and ±16g. g is the Earth's gravity acceleration, whose value is 9,81 m/s², and detects changes in inclination angle lower than 1º. This chip was manufactured by Analog Devices. This is the chip's block diagram.
