An ultrasonic probe and an ultrasonic detecting device provided with the ultrasonic probe. The ultrasonic probe includes: an ultrasonic transducer array configured to transmit and receive ultrasonic waves; a conducting device disposed at the front end of the ultrasonic transducer array, and the conducting device includes a fluid chamber filled with fluid. The fluid chamber has an opening and an energy receiving port which are in communication with each other, and the opening is disposed on a front surface of the conducting device and covered by an elastic film; an energy applying device, connected to the energy receiving port to apply energy to the fluid within the fluid chamber to make the elastic film vibrate so as to generate a shear wave.

A system includes a first transducer configured as an actuator. The first transducer is in communication with a surface of a structure. A second transducer is configured as a sensor. The second transducer is in communication with the surface. A third transducer is configured as a sensor. The third transducer is in communication with the surface and separated from the second transduce by an area. A digitizing unit receives signals from the second transducer and the third transducer. The digitizing unit communicates a plurality of frequency signals for the first transducer. A computing unit communicates the plurality of frequency signals to the digitizing unit, receives digitized signals from the digitizing unit, and calculates a Frequency Response Function from the digitized signals. Changes to the Frequency Response Function indicate a change to physical properties of the structure.

Sonar systems and related methods are provided. A sonar system for generating one or more sonar images includes first and second transducer elements each having at least one emitting face. The sonar system also includes a sonar signal processor in electronic communication with the first and second transducer elements to cause transmission of signals from the first and second transducer elements to cause at least one first acoustic beam to be emitted from the first emitting face in a first beam direction and at least one second acoustic beam to be emitted from the second emitting face in a second beam direction. The first and second transducer elements are positioned such that a gap is formed therebetween. The gap is configured to facilitate movement of a fluid therein so as to contribute to an emission of sound power in both the first beam direction and the second beam direction.

A method for separating a second fluid or a particulate from a host fluid is disclosed. The method includes flowing the mixture through an acoustophoretic device comprising an acoustic chamber, an ultrasonic transducer, and a reflector. The transducer includes a piezoelectric material driven by a voltage signal to create a multi-dimensional acoustic standing wave in the acoustic chamber. A voltage signal is sent to drive the ultrasonic transducer in a displacement profile that is a superposition of a combination of different mode shapes that are the same order of magnitude to create the multi-dimensional acoustic standing wave in the acoustic chamber such that the second fluid or particulate is continuously trapped in the standing wave, and then agglomerates, aggregates, clumps, or coalesces together, and subsequently rises or settles out of the host fluid due to buoyancy or gravity forces, and exits the acoustic chamber.
