This spontaneous electrical dipole moment can be repeatedly transmitted between two or more equivalent states or directions when applying an external electric field – a property used in a variety of ferroelectric technologies, for example, nano-electronic computer memory, RFID card, medical ultrasonic transducer, Infrared cameras, submarine sonar, vibration and pressure sensors and precision devices.
