Life-sciences and medical design equipment disciplines have multi-faceted requirements for motion control, spanning a spectrum from high-precision positioning systems to reliable, low-cost, and compact drive components with ultra-low power consumption. Since progress goes hand in hand with continuous miniaturization and demand for higher speed and throughput, piezoceramic drives can satisfy many of these requirements. Originally developed for nanometer-precision motion, piezoelectric motion principles are proving highly adaptable to new configurations and modalities. Recently-developed systems have overcome the former limitations familiar from classical piezo mechanisms.

Different from traditional motors

Piezo devices have several advantages over classical motion control components:

  • Sterile / high bake-out temperatures
  • No lubricants required
  • Non-magnetic principle (MRI compatible)
  • Vacuum compatible
  • Smaller, higher force and faster response
  • Direct linear motion w/o conversion losses


  • For medical and biotechnology applications, piezoelectric motors can overcome problems of traditional motors since they neither create electromagnetic interference, nor are they influenced by it, eliminating the need for magnetic shielding. This feature is particularly important for motors used within strong magnetic fields, such as those seen in MRI equipment.

    Application Examples

  • Piezo motors for uniform force while pipetting
  • Piezo transducers for generation of homogenous aerosols
  • Piezo scanners for precision in visualization and microscopy
  • Piezo transducers for reliable flow measurement and bubble detection
  • Piezo disks for compact and high performance micro-pumps
  • Piezo flexure actuators for precision dynamic nano-dispensers
  • Non-magnetic piezo motors for mri
  • Piezo ceramics for pumps, nebulizers and atomizers
