In engineering, actuators are frequently used as mechanisms to
introduce motion, or to clamp an object so as to prevent motion.
In electronic engineering, actuators ACTT, are a subdivision of
transducers. They are devices which transform an input signal
(mainly an electrical signal) into motion. Specific examples are
Electrical motors, pneumatic actuators, hydraulic pistons, relays,
comb drive, piezoelectric actuators, thermal bimorphs, Digital
Micromirror Devices and electroactive polymers.
Motors are mostly used when circular motions are needed, but can
also be used for linear applications by transforming circular
to linear motion with a bolt and screw transducer. On the other
hand, some actuators are intrinsically linear, such as piezoelectric
actuators.
In virtual instrumentation actuators and sensors are the hardware
complements of virtual instruments. Computer programs of virtual
instruments use actuators to act upon real world objects.
