Why should I use a Miga memory metal actuator instead of a solenoid?
Solenoids (and, in fact, every other motor in the world) are much heavier than Miga memory metal actuators for comparable force output. Solenoids are also ON/OFF devices, and do not have speed, force, or position control; all of which are possible with Miga motors. Miga shape memory actuators also produce a constant force throughout the entire stroke, while the output force of a solenoid drops dramatically after the first 10% of motion.
