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 harves
