When some dielectrics are deformed by external forces in a certain direction, the internal polarization phenomenon causes opposite charges on both surfaces, and when the external force is removed, it returns to the uncharged state; and when the force direction changes At the time, the polarity of the charge changes. The amount of charge generated by the force of the crystal is proportional to the amount of external force. This phenomenon is called the positive piezoelectric effect. Conversely, if a certain electric field is applied to the crystal, the crystal itself will be mechanically deformed, the external electric field will be withdrawn, and the deformation will disappear, which is called the inverse piezoelectric effect.
