Piezo Stages

Piezo stages are used for precise and dynamic motion in a single axis or multiple axes (X, Z, XY or XYZ stages). Flexure frames are solid state with high stiffness, zero backlash, no particulate and practically infinite life. Flexure stage travels range from approximately 20µm to 1000µm. With a low-noise drive signal, the precision is limited only by the feedback resolution; ideal for nanopositioning.

Benefits of Piezo Flexure Stages

  • Analog position resolution can be as good as drive signal and feedback resolution
  • Single axis or combine for multi-axis motion
  • Low off-axis roll and tilt of output
  • High dynamic performance
  • No backlash in motion
  • High load capability and configurable output platform
  • Customizable mounting configurations

Piezo Stages for your Application

DSM is your "one-stop" solution for design, manufacturing, and product support. For over 20 years, DSM has created OEM flexure based designs. Examples of custom designs include combinations of the following: 

  • Ultra-high vacuum environments
  • Magnetic environments (e.g. MRI machines)
  • High, low or wide operating temperature range
  • Integrated position sensors for closed loop control

Why use a piezo stage instead of a piezo actuator?

Both piezo stages and piezo actuators use one or more piezoelectric stacks inside a metal frame. The metal frame provides preload and amplifies the stroke of the stack. Piezo stages use extra material around the actuator frame to guide the path of motion in a desired manner, either by making the displacement more stable, or by coupling multiple actuators into a more complex system. In this way, a single stage can be designed to have combinations of linear and rotational motion, such as XY stages, or Z stages with tilt. Piezo stages have more linear stability, higher load capacity, and larger mounting surfaces compared to non-stage actuator architectures.

DSM produces stages with linear and rotary motion; with single-axis or multi-axis control:

Piezo Stage Architecture Description
Piezo Stage – the FPA actuator architecture is integrated with additional guidance flexures and output platform.

Piezo Stage vs Piezo Motor Stage

DSM offers both Piezo stages and piezo motor stages. Flexure stages rely only on piezoceramic stack expansion to move and so have limited travel. DSM's piezo motor stage has practically limitless travel by using piezo structures in a step-and-repeat configuration to take steps along the axis of motion. See DSM’s I-20 piezo motor and MD-90 closed-loop piezo motor driver.

Integrated Feedback and Closed Loop Control

Closed loop control mitigates the hysteresis and thermal effects that typically occur with a piezoelectric device. DSM can integrate position sensors into most architectures for closed loop control. Example: DSM can assemble your piezo stage with an integrated optical encoder (or other device) removing the need to choose and install it yourself. Contact DSM for closed loop control options.
