This uses the concept of change of capacitance by a change in overlapping area and distance between the capacitor plates. An electrical transducer is a device which is capable of converting physical quanties into a proportional electrical quantity such as voltage or electric current. When the transducer converts an electrical signal into another form of energy, such as sound (which, incidentally, is a pressure field), light, mechanical movement, it is called an actuator. Which of the previously mentioned examples is an actuator? Many of the transducers used in everyday life operate in both directions, such as the speakerphone on certain intercoms. A SEMINAR If a magnetostrictive material is magnetized, it strains.Conversely, if an external force produce a strain in a magnetostrictive material thean external force produce a strain in a magnetostrictive material, the An actuator is a device that actuates or moves something.
