Piezoacoustic Transducer

Application ID: 1477

A piezoelectric transducer can be used either to transform an electric current to an acoustic pressure field or, the opposite, to produce an electric current from an acoustic field. These devices are generally useful for applications that require the generation of sound in air and liquids. Examples of such applications include phased array microphones, ultrasound equipment, inkjet droplet actuators, drug discovery, sonar transducers, bioimaging, and acousto-biotherapeutics.

This example shows how to couple piezoelectric vibrations in a transducer to an acoustics pressure wave in a fluid such as air or water. The physics that are coupled and solved are piezoelectric stress-strain, an electric field, and pressure acoustics in a fluid.

This model example illustrates applications of this type that would nominally be built using the following products:
