And multilayer piezoelectric structures especially multilayer piezoelectric actuators often failured from the edge of internal electrodes.

压电层合结构尤其是层合状压电致动器，多在内电极端部发生断裂。

Piezoelectric sensors and actuators may be considered as multilayer laminated composites consisting of alternating layers of piezoelectric and non-piezoelectric materials.

压电传感器和致动器都可以看成是一种复合材料层合板结构，由压电材料层和非压电(弹性)材料层交替铺设而成。
