The piezoelectric actuator is a kind of device. Which converts electrical energy into a mechanical displacement or stress based on a piezoelectric effect.
The piezo stack (PZT stack) will be installed in the actuator. Piezo stack is also called multilayer piezoelectric ceramic actuator, piezo actuator, piezoelectric stack actuator.
It’s a kind of industry ceramic with a very complex process. In He-Shuai Ltd, we used tape casting technology to produce the piezoelectric ceramic.
“Multilayer” means lots of piezoelectric ceramic discs. We can do some of the shapes for you. Like: disc, ring, cylinder, square with hole, and so on.
You can check our product list for standard models before you buy piezoelectric stacks. Or you can send us your requests for OEM orders.
