An actuator is a mechanism for turning energy into motion.
Actuators can be categorized by the energy source they require to generate motion. For example:
- Pneumatic actuators use compressed air to generate motion.
- Hydrolic actuators use liquid to generate motion.
- Electric actuators use an external power source, such as a battery, to generate motion.
- Thermal actuators use a heat source to generate motion.
This tutorial from the SouthWest Center for Microsystems Education explains how actuators work.
