Technical Field

The invention relates to the field of piezoelectricity, in particular to a power generation device based on a piezoelectric material.

Background

Piezoelectric materials are crystalline materials that develop a voltage across their two terminals when subjected to a compressive force. Crystalline material that when subjected to a compressive force develops a voltage across the two terminals. When a weight is placed on a quartz crystal, some surface of the crystal will generate charges, the amount of which is proportional to the pressure. This phenomenon is called the piezoelectric effect. The mechanism of the piezoelectric effect is: the crystal with piezoelectricity has low symmetry, when the crystal is deformed under the action of an external force, the relative displacement of positive and negative ions in a unit cell ensures that the centers of the positive and negative charges are not superposed any more, so that the crystal is subjected to macroscopic polarization, and the surface charge density of the crystal is equal to the projection of the polarization strength in the surface normal direction, so that opposite charges can appear on two end surfaces when the piezoelectric material is deformed under the action of the pressure. Conversely, when a piezoelectric material is polarized in an electric field, the material deforms due to the displacement of the charge center.
