SENSORS & ACTUATORS

Stack Actuators

Multilayer Piezoelectric Actuators
SensorTech's multilayer piezoelectric actuator is a device consisting of a number of piezoelectric elements in a stack. The elements are connected in parallel through an internal electrode structure. 

Features

  • Compact and Lightweight
  • Solid state
  • 50% conversion efficiency
  • Fast response
  • Displacement proportional to
    applied voltage
  • Large force
  • Broad operating temperature range
  • Excellent stability

Applications

  • Positioning devices
  • Motors and relays
  • Translators
  • Displacement devices
  • Deformable mirrors
  • Pumps

Materials and Geometries
Multilayer stack actuators may use a variety of piezoelectric materials in a range of shapes and sizes. The tables below provide properties of multilayer stack actuators that use BM500 and BM400 with both square and ring geometries. Actuators that use BM500 have higher displacement but also have higher capacitance and dissipation factor. Actuators using other materials and geometries are available upon request.
