Electrostrictive introduction

Electrostriction Some polycrystalline materials, such as lead zirconate titanate ceramics, have spontaneously formed molecular groups, so-called electrical domains, which have a certain polarization, and the length along the polarization direction is often different from other directions. When an external electric field is applied, this electric domain will rotate to make its polarization direction as much as possible consistent with the direction of the external electric field. Therefore, the length of this material along the direction of the external electric field will change. This phenomenon is called electrical Caused by the telescopic effect.
