What is an actuator?

An actuator converts electrical energy into mechanical motion.

What is the piezoelectric effect?

The piezoelectric effect refers to the interaction of mechanical motion and electrical tension in solids. It is based on the phenomenon of certain materials (piezo materials) producing an electrical charge as the result of their deformation (direct piezoelectric effect). Conversely, these same materials will deform in response to electrical tension (indirect piezoelectric effect). Therefore, the piezoelectric effect is a link between electrostatics and mechanics.

What is a piezomotor?

A piezomotor is a drive device based on the piezoelectric principle whereby electricity is converted into kinetic mechanical energy by a piezomaterial.
