Ultra High Temp Nitinol Actuator in Boiling Water
We have worked with NASA in the development and testing of Ultra High Temperature (UHT) Shape Memory Alloys. This actuator features Nickel-Titanium-Palladium (NiTiPd) and Nickel-Titanium-Platinum (NiTiPt). These alloys have a very steep transition temperature in the...

Center Post Rail Gun Actuator
Twelve layer printed coils are used to launch a small Neodymium Iron Borate magnet. We use short 10 ms pulses in the coil at 30 Volts.Our Offices Fishers, IN, USA Silverton, OR, USAContact Us Click here for our web form, we'll get right back to you.Office Hours...
Nano Muscle Nitinol Walking Bug
This actuator used two linear NanoMuscle motors to provide the realistic bug-like walking motion. It was a self-contained critter powered by it's own internal battery pack. It used 6" of 0.0035" diameter of a custom alloy Nitinol.Our Offices Fishers, IN, USA...

Nitinol Actuators in series explanation
The longer the length of wire, the higher the resistance, thus drawing less current for a given operating voltage. In this demo we are operating three life vest trigger mechanism in series using a single MOSFET current switch. Our Nitinol Actuation Model predicted...
High Speed Nitinol Actuation with fan forced air
This is 91 mm long S100 actuator which has 2.5 mm of stroke. It has 73 mm of 0.005 HT Flexinol wire. We operate it in a strong airflow at 9 Volts as part of our study on enhanced cooling to verify fit to our Nitinol Actuation Model.Our Offices Fishers, IN, USA...
High speed Flexinol LT cooling with Mineral Oil and Dry Ice
This video shows part of a study to determine enhanced cooling for rapid cycling of Nickel-Titanium. We show 20" of 15 mil Flexinol LT cooling in 2.5 seconds to full recovery in Mineral Oil and Dry Ice using a 15 pound spring. Actual data compared to data predicted...
Active Shock Damper Actuator
This was a technology demonstrator that flew on a university Cubesat satellite. The technology was used to damp motion of the spacecraft after momentum events such as solar array deployment. Active dampers are used in tall buildings to lessen the effects of building...
Shape Memory Alloy Actuator Actuated in Liquid Nitrogen
Nitinol can operate in the most extreme environments including this one at minus 356 degrees Fahrenheit. Our Nitinol Actuation Model predicted we would need to energize this Flexinol actuator at 30 Volts for 0.2 seconds to overcome the cooling effect of the liquid...
High speed Flexinol HT cooling with Mineral Oil and Dry Ice
This video shows part of a study to determine enhanced cooling for rapid cycling of Nickel-Titanium. We show 20" of 15 mil Flexinol HT cooling in 2.2 seconds to full recovery in Mineral Oil and Dry Ice and a 15 pound spring. Experimental data matches our model data...
SMA Actuator Build Process
Six individual U-loop SMA actuators: 0.02” diameter SMA wiresMechanically in parallel, electrically in seriesEach actuator has a tuned overstress protection switch that removes power from entire circuit if any actuator is in overstress7mm stroke, 112# force~2 amps at...
Nitinol Terminology
