OPHION Helical Shape Memory Alloy (SMA)
Actuator Products

QorTek patented OPHION hollow helical geometry SMA actuators introduce a new set of options for SMA actuation. The tubular construction enables the devices to be either/or activated by both fluid or gas flow or by more conventional electrical connected power source.  Typically manufactured from alloy grade SMA (Nitinol), (coined "Alloy H" by SAES Memory Corporation), these can be manufactured and trained in a wide range of tubular cross section geometries and pre-actuated form factor sizes all varying from mm to many cm.

These large motion devices can be activated either by electrical charge, gas emission or fluidic catalyst.  QorTek “pre-trains” these helical springs to provide the correct displacement characteristics needed by the customer application.  Once trains these devices sit in the dormant ‘Austinite’ state until activated by an electrical or thermal catalyst.  Correctly designed, the catalyst will cause a large displacement to occur in the actuator with significant applied force.

 

Thin film lithium polymer batteries have demonstrated that they are capable of delivering the required amount of burst current (up to 1.7A) and still remain at near full capacity. A single battery can easily provide enough current to simultaneously activate multiple QorTek Helical, Serpentine or Arch SMA devices.

QorTek can design the OPHEON actuator geometry to your specified product or application needs and constraints with optional matched high efficiency trigger source.

OPHION devices are available in a wide range of standard and custom configurations. Please contact our experienced engineering staff for support in evaluating your development or product needs and our sales department for estimated delivery scheduling.

QorTek can provide a wide range of (low power requirement) custom OPHION Helical, Arch or Serpentine SMA actuators featuring large force × displacement characteristics at manageable investment costs. Please contact our experienced engineering staff for supporting the best solution to your actuation device or system requirements. QorTek can design the dimensions of a surface or subsurface mount geometry to your specified need and constraints and provide a matching very high efficiency trigger source to activate the mechanism.

OPHION Arch SMA Actuators

By providing SMA plate with a simple arch geometric memory the resulting actuator has very low profile but can induce large force motion.  The heat transfer of the flattened material is superior reducing the overall power necessary to activate its motion. Correctly pre-trained, such arch actuators provide a low cost solution to high force  plus large displacement requirements.  QorTek can design the dimensions and arch geometry to your specified need and constraints and provide a matching very high efficiency trigger source to activate the mechanism.

Serpentive SMA Actuators

(shown here with transparent cover for visibility)

By bending the SMA into a serpentine shape it enables low profile integration of large force × displacement actuation capability.  The heat transfer of the flattened material is superior reducing the overall power necessary to activate its motion.

 

OPHION Arch and Serpentine devices are available in a wide range of configurations. Please contact our experienced engineering staff for support in evaluating your development or product needs and our sales department for estimated delivery scheduling.
