Volume ready customizable nitinol actuator
Volume Ready Customizable S125
The S125 is a volume-ready Shape Memory Alloy wire actuator, with a MOSFET switching & protection circuitry on a Printed Circuit Board substrate. The ideal uses are latch or trigger release mechanisms for battery-powered devices.
The S125 is a short-stroke latch-release or trigger-release mechanism featuring totally silent operation and thin profile typical of our Shape Memory Alloy constant-force actuators. (more…)
Advanced Low Profile SMA Actuator
Advanced Low-Profile SMA Actuator
-Our custom MOSFET/Protection Circuit is on each PCB-Actuator
-Typical 3-wire interface: Power, Ground, and Enable. When you raise the Enable line logic level HIGH, we energize until you lower the Enable. The actuator moves to the end of stroke, and ‘holds’ there safely until you release it (set Enable to Low).
-The actuators typically operate from 3 to 12 volts
-Typical stroke is in the 0.1″ to 0.25″ range
-Typical force is in the 0.5# to 5.0# range (more…)
Oceanic Safety Systems Advanced Lifesaving Diver Vest SMA Actuator
Oceanic Safety Systems Advanced Lifesaving Diver Vest SMA Actuator
We assisted inventor, Dr. Terry Maas, with the actuating technology for his patented, lifesaving vest. Originally designed to protect Freedivers, it soon became apparent the lifesaving vest had a much broader appeal among all those in danger of drowning.
- Oceanic Safety Systems (OSS) is currently working with two well-known life vest manufacturers—one for the Navy SEALS, the other for surfers.
- OSS continues to improve its own line of programmable, submersible, life vests for mariners, freedivers, and surfers.
- One of the uses of the OSS actuator is to protect valuable goods from sinking—from small equipment to larger items, such as jet skis.

Credit Card Scale High Force Nitinol Actuator
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 applications to be volume ready. This design features our patented technology that multiplies the stroke of single wires allowing for longer strokes in small packages.

Drone Payload Release
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 used across a wide range of voltages, from 3.7 Volts – 30 Volts. They can be actuated with as little as 5 watts of power and can be made to hold in the actuated state with roughly 15% of the actuation power.

1/4-Pound One-Way Solid State Latching Actuator
1/4-Pound One-Way Solid State Latching Actuator
A magnetic detent on one printed coil provides a preferred location for the magnet that is shared between the two coils. When the coil is energized the magnet escapes the detent and travels to the opposite side. When the coil is de-energized the magnet returns to the detent position.

Side Flex Latch Nitinol Actuator
Side Flex Latch Nitinol Actuator
This prototype actuator provided actuation along the narrow axis of the actuator. The idea was to use the music wire flexures as biasing springs and to make it as thin as possible. It is capable of developing roughly 1 pound of force without exceeding a design limit of 25 ksi for high cycle capability. Dynalloy recommends 25 ksi as their “million cycle” force for Flexinol.
