“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.”
