The piezoelectric actuators on this page include modular, screw, and replaceable-tip piezo actuators. We also offer piezo inertia, vacuum-compatible piezo inertia, and amplified piezo actuators.

A piezoelectric actuator is a transducer, used to change an electrical signal into an accurately controlled physical displacement or stroke by using piezoelectric effect based on electromechanical coupling rather than electromagnetic induction.

Piezoelectric actuators are a class of actuators that precisely transfer input electric energy into displacement, force, or movement outputs efficiently via inverse piezoelectric effect-based electromechanical coupling.

The precise movement control afforded by piezoelectric actuators is used to finely adjust machining tools, lenses, mirrors, or other equipment. A piezo actuator can be used to control hydraulic valves, act as a small-volume pump or special-purpose motor, and in other applications requiring movement or force. Get A Quote On Parts

Amplified piezoelectric actuators are specific actuators using piezoelectric materials as active material and have a specific design to overcome traditional limitations of classical direct piezoelectric actuators, [1] the limited stroke.

A piezo actuator can follow a sinusoidal signal up to its resonant frequency. Beyond this point, its inertia inhibits it from keeping up with electrical excitation. From a practical standpoint, it’s a good idea to limit operation to ~3/4 Fr.

The piezoelectric actuator is a kind of actuation device that acts through the inverse piezoelectric effect. Due to advantages of high precision, low power consumption, compact size, and flexible structure design, they have a wide range of applications in optics, robotics, microelectromechanical systems, and so on.

A Piezo actuator, also commonly referred to as a piezo linear actuator, is a device that converts electrical energy directly into linear motion using the piezoelectric effect. This effect occurs when we apply mechanical force and stress to certain materials, such as quartz and ceramics.

A piezo actuator converts electrical energy into mechanical motion through the inverse piezoelectric effect. When a voltage is applied to a piezoelectric material (e.g. PZT), it deforms, producing extremely small, precise linear displacements. This makes them ideal for ultra-fine positioning on a nanometer scale.
