Positive piezoelectric effect

The positive piezoelectric effect means that when the crystal is subjected to an external force in a fixed direction, an internal electrode phenomenon occurs and an opposite charge is generated on two surfaces at the same time; when the external force is removed, the crystal returns to an uncharged state ; When the direction of the external force changes, the polarity of the charge also changes; the amount of charge generated by the crystal force is proportional to the magnitude of the external force. Piezoelectric sensors are mostly made using the positive piezoelectric effect.
