Credit Card Scale High Force Nitinol Actuator

We have found that printed circuit boards (PCB) are great substrates on which to build Nitinol actuators. Using standard PCB design and assembly technology, high precision components and circuitry can be pick and placed along with actuator components. This allows for...

Drone Payload Release

These prototype devices have been used as drone payload release mechanisms and for protecting drugs in high security medical carts. They can be made very thin (less than 2 mm) and lightweight (less than 1 ounce) and can use very little energy to actuate. They can be...

Ganged Over-Stress Protected SMA actuator

This actuator has 7 mm of stroke at 125 pounds of force. These three ganged actuators operate in series and are an example of an over-stress protected actuator.Our Offices Fishers, IN, USA Silverton, OR, USAContact Us Click here for our web form, we'll get right back...

Crimps on 0.015″ diameter Flexinol

High strength crimps applied to Dynalloy's 0.015" diameter Flexinol capable of holding 30 pounds. The wire breaks before the crimp comes off. These crimps go way beyond anything else commercially available.Our Offices Fishers, IN, USA Silverton, OR, USAContact Us...

Nitinol Actuator Over-Stress Protection

Nitinol actuators are very easily damaged if the stress exceeds roughly 40 ksi or if the temperature exceeds 150 degrees C. This is a demonstration of mechanical over-stress protection in which flexures deflect very short distances when an engineered or pre-determined...
