P-878 DuraAct Power Patch Transducer

P-878.A1, dimensions in mm

The DuraAct Power multilayer patch transducers use the longitudinal or d33 effect, which describes an elongation parallel to the electric field E and the polarization direction P of the piezo actuator. The d33 piezoelectric charge coefficients for longitudinal displacement are considerably higher than the d31 coefficients for transversal displacement, used by all-ceramic patch transducers (Source: Wierach, DLR).

DuraAct Power多层贴片换能器使用纵向或d33效果，它描述了平行于电场E和压电促动器极化方向P的纵向方向。所有陶瓷贴片换能器所使用的纵向位移的d33压电电荷系数比横向位移的d31压电电荷系数高很多。（来源：Wierach，DLR）。
