2. Tonpilz - Wikipedia

   en.wikipedia.org/wiki/Tonpilz

   The term tonpilz or "acoustic mushroom" may refer to a certain type of underwater electro-acoustic transducer. By sandwiching active (i.e. piezoelectric or magnetostrictive) materials between a light, stiff radiating head mass and a heavy tail mass, the transducer can effectively operate as either a projector (source) or a hydrophone (underwater acoustic receiver).

3. Sonotrode - Wikipedia

   en.wikipedia.org/wiki/Sonotrode

   A sonotrode usually consists of a stack of piezoelectric transducers attached to a tapering metal rod. The end of the rod is applied to the working material. An alternating current oscillating at ultrasonic frequency is applied by a separate power supply unit to the piezoelectric transducers. The current causes them to expand and contract.

4. Piezoelectric micromachined ultrasonic transducer - Wikipedia

   en.wikipedia.org/wiki/Piezoelectric_micro...

   Piezoelectric micromachined ultrasonic transducers (PMUT) are MEMS-based piezoelectric ultrasonic transducers.Unlike bulk piezoelectric transducers which use the thickness-mode motion of a plate of piezoelectric ceramic such as PZT or single-crystal PMN-PT, PMUT are based on the flexural motion of a thin membrane coupled with a thin piezoelectric film, such as PVDF.

   After nearly a year of waiting, Amazon (AMZN) users can now buy a Hyundai (HYMTF) vehicle through the online retailer. Starting today, Amazon car shoppers in 48 cities, including New York, Los ...

6. Phased array ultrasonics - Wikipedia

   en.wikipedia.org/wiki/Phased_array_ultrasonics

   The PA probe consists of many small ultrasonic transducers, each of which can be pulsed independently.By varying the timing, for instance by making the pulse from each transducer progressively delayed going up the line, a pattern of constructive interference is set up that results in radiating a quasi-plane ultrasonic beam at a set angle depending on the progressive time delay.
