Electronic devices electromechanical actuators

Nearly all domestic appliances are using more and more electronics. Mechanical functions are replaced by electronic devices, mainly sensors and electromechanical actuators (such as pumps or electromotors) and microelectronic control systems. 

The broad application of relaxor ferroelectrics in the modern sensors, actuators, high performance electromechanical transducers and other electronic devices generates the constant interest in investigation and fabrication of these materials. 

A more influential market driver is the growth of electric and electronic systems on vehicles. The demands come not only from a variety of comfort, convenience, communications, and entertainment features, but also from an evolution to electromechanical operation for many auxiliary devices that to date have been purely mechanical, such as power steering, valve train actuation, braking, suspensions, and air conditioning, among others. Moreover, power train electrification enables new levels of driver responsiveness and controllability in addition to fuel economy benefits.
