Piezotechnics Piezo Stack Actuators - Piezo Actuators - Piezo

To put it in a nutshell: The idea of piezo stack actuators is as simple as it is effective: Piezo are made of active material. The length of the piezoelectric stack is directly controlled by applying an electrical voltage. When the solid piezoelectric body expands immediate reaction take place which provides strong, fast, and precise actuation. This effect is most suitable for innovative positioning tasks.

Piezo actuators for piezoelectric nanopositioning

Using the inverse piezoelectric effect of so-called PZT ceramics- the piezo drives (piezo actuator) realize extremely high-resolution nanopositioning:An applied voltage generates an electric field in the ceramic- which leads to an alignment of the structure in the lattice structure of the ceramic:

Integrated Piezo Actuators - Positioning

Piezo amplifiers for PICMA ® Multilayer Piezo Actuators offer an output voltage of up to 130 V. Amplifiers with high output current allow dynamic operation of the actuators and precise positioning while requiring low power.

Piezoelectric Actuator - an overview | ScienceDirect

Piezoelectric stack or multilayer actuators are manufactured by stacking up piezoelectric disks or plates: the axis of the stack being the axis of linear motion that occurs when a voltage is applied. Tube actuators are monolithic devices that contract laterally and longitudinally when a voltage is applied between the inner and outer electrodes.

Linear Piezo Stack

They are superior to conventional multilayer actuators in industrial applications and high-endurance situations, where they show substantially longer lifetimes both in static and dynamic operation· PDF Brochure | Piezo Stack Actuator Specs, Drawings, Part numbers_ P-840 · P-841 Medium Load Preloaded Piezo Linear Actuators _ Closed-Loop Option

What are piezo actuators? - Linear Motion

Longitudinal piezo actuators also have high resonant frequencies: which makes them well|suited for dynamic applications. Piezo stack actuator Image credit: Noliac Shear actuators. Shear actuators are similar to longitudinal versions: in that they consist of multiple layers of piezo elements.

Piezo actuators and piezo motors: linear motion

Piezo actuators are available in various configurations- including longitudinal- shear- tube- and contracting versions: A piezo motor combines a piezo actuator (typically a longitudinal- or “stack-” actuator) with other mechanical elements to produce longer stroke lengths: Piezo motors include ultrasonic- inertia- and stepper types:
