Linear actuators are devices that convert any rotary or spinning motion into a linear (straight) motion. In simple words, they help machins move forward and backward. The most basic type of linear ...

The evolution of science has led to many discoveries, including linear actuators that are heavily used in different industries. A linear actuator is a device that helps to convert electrical energy ...

But linear actuators built around a novel "rolling-ring" design from Amacoil Inc., Aston, Pa. (www.amacoil.com), use compression and friction forces to smooth rather than impede linear motion.

How does a piezoelectric transducer (actuator) work? Modern Piezo actuators are based on thin piezoceramic layers manufactured in a co-fired process to form a monolithic unit.
