Research Progress on the Characteristics and Mechanism of Applied Field-Induced Fatigue in Piezoelectric Ceramics

Being considered as a dominant factor for its failures, the field-induced fatigue of piezoelectric ceramics is a gradual degradation of piezoelectric properties under applied cyclic loading and becomes a hot topic in the world in recent years. The fatigue mechanisms and influential factors of piezoelectric ceramics under applied electric field or multi-fields (stress-electric-temperature) were reviewed in this paper. Furthermore, the development trends in this area were proposed too.
