英文摘要：

The piezoelectric energy harvesters have been developed, and the corresponding performance has been improved in recent years. However, the electromechanical conversion efficiency of the piezoelectric energy harvester is still low, which is restricted due to the low electromechanical conversion performance of the piezoelectric ceramic itself. It is thus significant and meaningful to prepare piezoelectric ceramics with high electromechanical conversion performance. This paper mainly reviews research progress in the property modulation of piezoelectric ceramics with high electromechanical conversion performance, i.e., performance requirement of piezoelectric ceramics for energy harvesting under the non-resonant and the resonant state, the comparison of electromechanical conversion performance between the lead-based and lead-free piezoelectric ceramics for energy harvesting, and various design methods of piezoelectric ceramics to obtain high electromechanical conversion performance. In addition, some questions and research aspects for future studies in this field are proposed.
