Nitinol Actuators by Miga Technologies LLC

Latch Release Mechanisms

All of the actuators below can be used to release latches. A nitinol powered latch release can be many times smaller and lighter than a solenoid powered latch release. Nitinol actuator powered latch releases will also use a small fraction of the power.

Volume ready customizable nitinol actuator

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...

Advanced Low Profile SMA Actuator

Advanced Low Profile SMA Actuator

Here is our latest 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...

Laptop lid Nitinol actuator latch

Laptop lid Nitinol actuator latch

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...

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...

Drone Payload Release or Medical Cart Latch Release

Drone Payload Release or Medical Cart Latch 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...

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...
