Noliac piezo actuators can be produced with a through hole. This feature is widely used in optical applications, where the inner hole serves as a clear aperture for light beams or optical fibers. The through hole can also be used for applying preload, or for instance to install measuring equipment in the axis of the stack.
We can produce both plate actuators and plate actuator stacks as well as shear and shear stacks with a through hole.
