NEC/TOKIN - Resin Coated Piezo Actuators

Piezoelectric Multilayer Actuators

AE Series

NEC Tokin AE Series Piezoelectric Actuators
Thick Coating (Type F) Thin Coating (Type DF)

Outline

NEC Tokin's multilayer piezoelectric actuators are manufactured by NEC/TOKIN Corporation of Japan and distributed by Micromechatronics Inc in USA.

Compared to conventional bulk piezoelectric actuators, they are similar in size but can generate higher displacement and force at low voltages, thanks to their multilayer structure.

Especially, the resin-coated AE series actuators feature compact size and wide variety in shape for use in ultra-fine positioning mechanisms and drive sources for various applications.

Features

Special ceramics developed by NEC TOKIN are used in piezoelectric ceramic elements. As compared with conventional actuator elements, NEC TOKIN's multilayer actuators have the following advantages:

  • Large generated force: 3,500 N/cm2.
  • High-speed response: Driving up to about 1/3 of self-resonant frequency (in several ten kHz) is possible.
  • Accurate positioning: Controllable in nm.
  • Low power consumption: Can be retained at the leakage current (100?A or less).
  • Very small size

Advantages over electromagnetic actuators

  • Superior response
  • High resolution for positioning
  • Low power consumption
  • No electromagnetic noise

Advantages over bimorph piezoelectric actuators

  • High energy conversion efficiency (around 7 times the
  • energy conversion efficiency of the bimorph type actuator),
  • and low power consumption
  • Large generated force
  • Stable displacement, and reduced shift and creep phenomena
  • Higher response speed (more than 100 times the response
  • speed of the bimorph piezoelectric actuator)

Advantages over stacked piezoelectric actuators

  • Compact (less than 1/10 the specific ratio of the stacked
  • piezoelectric actuator)
  • Low drive voltage, and ease of use
  • Inexpensive

Applications

Auto focusing of cell phone camera, Image stabilization on DSC, Positioning, Motors, Pumps, Valves, Vibration source, Vibration controls, Sensors, Mirror / Prism positioning, Manipulators, AFM, Printer, etc.
