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 laptop computer.  This actuator, like all of our newer actuators, has an on-board MOSFET switching and protection circuit.

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. (more…)

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 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.
