The piezoelectric ceramic stack is composed of a plurality of piezoelectric ceramic sheets stacked and bonded with epoxy resin. The free stroke of these stacks is significantly larger than that of a single piezoelectric ceramic chip, and the response time of sub millisecond level and the driving voltage range are kept low.
The square discrete piezoelectric ceramic stack consists of a plurality of piezoelectric ceramic chips stacked face to face and bonded with epoxy resin and glass beads. The free stroke of these stacks is significantly larger than that of a single piezoelectric ceramic chip, and the response time of sub millisecond level and the driving voltage range are kept low.
Two mounting surfaces of the piezoelectric ceramic stack are pasted with ceramic end caps. Flat end cap or hemispherical end cap can be selected. Flat end cap and hemispherical end cap have different advantages. When the load is along the translation axis of the actuator, the planar end cap can achieve large force transmission because of its large contact area. The hemispherical end cap allows the actuator to engage the off-axis load because the surface moves the force along the translation axis of the actuator. The ceramic end cap not only helps to distribute the force applied by the load on the mounting surface of the stack, but also helps to guide the force along the moving axis of the driver.
Each stack has an insulating ceramic layer on four sides to isolate moisture. Compared with epoxy coating, ceramic coating can isolate moisture better. For more severe environments, we also offer sealed discrete piezoelectric stacks. For convenience, these piezoelectric stacks are pre loaded with 75 mm long wires and wrapped in Kapton ® In the tape. We can also customize the size, voltage range and coating of the piezoelectric chip.

Two mounting surfaces of the piezoelectric ceramic stack are pasted with ceramic end caps. One end is a plane end cap, and the other end is a plane end cap or a hemispherical end cap.
