Custom piezoelectric benders

Most reliable piezoelectric actuators  

Features

Designed to exceed expectations

Our piezoelectric benders stand out not only for their outstanding performance but also for their super reliability and seamless integration. 

  • We have optimized our actuators for maximum displacement, allowing for precise and efficient operation. 
  • The design includes two protective layers that fully encapsulate the actuator, providing an extra layer of defense and ensuring super reliability even in demanding applications.
  • To ensure seamless integration, our actuators feature thermally isolated solder pads for electrical integration. This allows multiple rework cycles without risking any damage to the piezo layer.

FAQ

Question & Answer

Choosing between a unimorph and a bimorph piezoelectric actuator depends on your specific requirements. Unlike a unimorph, a bimorph actuator delivers symmetrical deflection/displacement in both positive and negative directions. Bimorph actuators typically offer higher displacement and greater flexibility in driving configuration. Additionally, bimorph actuators have a flat shape, while unimorph actuators have a curved shape. Conversely, unimorph actuators are lighter and more cost-effective compared to bimorph alternatives.

You can partially or completely remove the inactive part at the end of the actuator using a diamond saw, CNC, or scissors. The active (piezo) part can also be cut using a diamond saw. However, caution should be exercised as dust from the piezo material can be considered hazardous.

In general, longer piezoelectric benders tend to exhibit higher deflection and lower blocking force. The blocking force of an piezo bender is directly proportional to its width, while the displacement is relatively insensitive to the width. On the other hand, thicker bending actuators offer higher blocking force and slightly lower deflection. 

To drive the piezo actuators, you’ll require a function generator and a linear amplifier to amplify the signal. Commercially available options include piezo linear amplifier modules or benchtop units from brands like Piezo Drive and PI. If you prefer to develop a custom driver, you have several IC options to explore.

The piezo actuator can be manufactured as small as 10 x 2 x 0.5 mm, with virtually no limitations on its potential size.
