Overview
Piezoelectric pressure sensor is a typical self-generating sensor. It is the piezoelectric crystal material after the force in its surface charge generated by the positive piezoelectric effect of the conversion principle of the sensor.
Piezoelectric crystal is a machine-to-electrical conversion element that can measure those non-electrical quantities that can eventually be converted into forces, such as force, pressure, acceleration, etc., especially in explosive physics studies, wind tunnel experiments, biomedicine, electroacoustics, etc. In the technical field, piezoelectric pressure sensors have been widely used.
