Frequently Asked Questions

What are piezoelectric actuators used for?

Piezoelectric actuators are used in precision positioning systems, microfluidics, optical equipment, medical devices, ultrasonic cleaning, and industrial automation due to their high resolution, fast response, and compact size.

Can you customize piezo components?

Yes, we offer full customization including size, shape, electrode configuration, and performance parameters. Our engineering team supports OEM/ODM projects from prototype to mass production.

What is the advantage of multilayer piezo actuators?

Multilayer actuators operate at lower voltages (60–120V) compared to single-layer devices (hundreds of volts), while delivering high displacement and force in a compact stack design.

Do you supply samples?

Yes, we provide samples for evaluation. Contact us with your requirements and we’ll arrange shipment.
