Ultrasonic Components

    One of the important applications of piezoelectric materials is the ultrasonic signal-power conversions, i.e. used for generating and receiving ultrasonic waves. The development of ultrasonic science and technology is strongly dependent on the discovery of piezoelectric effects and the advance in piezoelectric material science. So far, most of ultrasonic devices have been made from piezoelectric materials.


    There are a variety of types of piezoelectric components. Different applications have different requirements upon the devices. Devices for ultrasonic processing, ultrasonic welding, ultrasonic cleaning, ultrasonic handling and ultrasonic long distance ranging require that the modules generate large high power and have high electroacoustic efficiency. Devices used for ultrasonic nondestructive detection, ultrasonic diagnosis and ultrasonic imaging require such performances as high sensitivity, broad frequency band and narrow pulse. So, piezoelectric materials with different performances should be chosen for different ultrasonic chips, and also different devices structures would be adopted.
