 SMA OIS Advantages


Voice Coil Motor (VCM) OIS

  SMA OIS Actuator


SMA OIS provides significant advantages over typical VCM OIS solutions including smaller size, better performance, large scale automated manufacturing, and lower cost.


Best performance in smallest footprint

  • Smallest actuation components, 25 µm wire, no position sensors or magnets
  • Can achieve small footprint (8.5mm or smaller)
  • High force actuator, good suppression with heavier optics
  • > 3 stop suppression performance @ > ±1° compensation
  • Low power consumption
  • Low camera orientation dependency (strong centering springs)
  • Meets mobile phone industry standard reliability requirements

High Capacity

  • Manufactured using automated processes
  • Ability to scale to high volumes quickly by replicating equipment
  • Leverages significant existing surplus HDD suspension capacity

Lowest Cost

  • Designed for automated web/sheet/assembly processing
  • SMA resistance feedback, no position sensors, low BOM
  • HTI proven hard disk drive components high volume / low cost business model
  • Highly automated for cost, quality, capacity, & capability
