The Versatility and Precision of Custom-Designed Piezo Devices

Piezo actuators utilize the piezoelectric effect to generate precise mechanical motion or force. They are made from materials like ceramics or crystals that deform when an electric voltage is applied.

This allows them to provide sub-nanometer resolution motion and fast response times in the microseconds range.

Some key advantages of piezo actuators:

High precision and repeatability - The piezoelectric effect allows accurate positioning and motion control down to the nanometer scale. Piezo actuators can move with precision that is orders of magnitude better than other types of mechanical actuators.

Wide dynamic range - Piezos can generate small precise movements as well as large forces up to thousands of newtons. This makes them highly versatile for different applications.

Fast response - Piezo materials respond very quickly to changes in voltage, allowing piezo devices to react within microseconds. This high speed makes them well suited for applications requiring fast actuation or vibration control.

Compact size - Piezo actuators provide a large force and motion range from a small package. This allows them to fit into tight spaces and miniaturized devices.

Low power consumption - Piezo actuators require very little input power to generate motion, improving energy efficiency.

Vacuum/cleanroom compatible - Piezo ceramics can operate in vacuum or cleanroom conditions unlike other actuator technologies that may outgas contaminants.

Custom piezo actuators are built to meet specific size, force, precision, and dynamics requirements for an application.

Key customizations include:

Varying materials and geometries to optimize properties like stiffness, power consumption, and operating temperature range.

Integrating piezos into complex assemblies with guides, flexures, and other mechanical elements.

Designing drive electronics and amplifiers to provide the required voltage inputs and control.

Creating arrays and stacks of multiple piezo elements to increase force generation.

Incorporating position sensors for closed-loop feedback control of the piezo motion.

Custom piezo solutions are ideal for applications like precision optics positioning, nanopositioning stages, atomic force microscopy, adaptive optics, vibration cancellation, fuel injectors, printers, and industrial robots. The high precision and fast response of piezos make them a versatile actuator technology.
