Actuation time can be in milliseconds and can meet locking force requirements of 100 pounds or more, while operating for more than 100,000 cycles.
A representative model in the new ThinLock TL-1 weighs 12 grams (0.4 oz), and is only 3.75mm (0.15” thick).
ThinLocks are ideal for automotive glovebox and center console locks, video screen dropdown release, secure medicine dispensing devices, server enclosures latches, removable module catches, storage boxes, chain of custody lockbox, luggage lock, mailboxes.
Pricing on our site is high as these devices are meant to be used as samples, but ultimate cost when brought to scale is projected to be in the low dollar range.

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…)
This prototype actuator was designed to provide 24 pounds of force and 3/8″ of stroke. There is a U-shaped Nitinol wire actuator on each side of the PCB (only one is currently installed), and they operate on a shared linkage. The SMA wire used here was 0.020″ diameter. The 3D printed ‘sled’ moves to the left when energized: compressing a spring that is pre-loaded to 12 pounds. If the load exceeds 12 pounds, the SMA wire can still contract by compressing the spring further. This protects the SMA wire from damage if the load exceeds the maximum design stress of the Nitinol wire.

-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…)
We designed the complex Nitinol actuating mechanism behind this dress that was worn on the runway at NY Fashion Week 2015 and at the Consumer Electronics Show (CES) 2016.
The Chromat Adrenaline Dress powered by Intel is composed of printed panels designed in an interlinked, expandable carbon fiber framework. When the garment senses adrenaline, the dress’s framework mimics the fight-or-flight mode and extends the wearer’s sensory system to form an imposing hourglass shape- signaling an augmented, empowered silhouette.
Intel’s Curie processor and a sweat sensor controlled the Nitinol actuating linkages to expand the dress.

Hydramax was an architectural model created by Future Cities Lab and installed in the San Francisco MOMA for 6 months. The model was designed to respond to museum goers with soft illumination and gentle organic operation of the roof panels. The silent organic operation was made possible by 60 of our Nitinol actuators embedded in the base of the model.

Originally developed for a European laptop manufacturer. The SMA actuator electronically releases the tablet from keyboard/CPU, so you can have a stand alone tablet/touchscreen. SMA is able to provide high-force motion even in the extremely tight spaces within a laptop computer. This actuator, like all of our newer actuators, has an on-board MOSFET switching and protection circuit.

This is a rotary Nitinol actuator bouncing between end limits. This actuator was designed to move the eyelids in a volume ready toy doll – Baby Bright Eyes. We called her Baby Fright Eyes, because it was so scary to look into her eyeballs, thus the failure of the product. Rotation was 60 degrees back and forth with a couple of ounces of force, using 0.003″ diameter Nitinol wire approximately 6″ long. Realistic eye movement was achieved drawing 2.4 Watts at 3.7 Volts. Our Enhanced Nitinol Actuation Model predicted a stress in the wire of 26 KSI, which closely matched experimental data.
