Historical Archive NIST piezoelectric transducer aids materials science 17 Jun 2002 An inexpensive acoustic wave transducer developed by NIST mechanical engineers soon may make it easier for ...

Some cool-mist humidifiers work by flinging water at a vaporizer, but our favorite kind uses a piezoelectric transducer. These work by using high-frequency sound waves to pound the surface of the ...

In fabricating a MEMS-based energy harvester, the piezoelectric transducer is designed to maximize the generation of electrical energy. In the example shown in figure 1, a floating mass is connected ...

You don’t need a big vessel to maximize coverage below the waterline — instead, opt for a wide-beam chirp-ready transducer with a high frequency range of 150 to 250 kHz. It’s ideal for tandem use with ...

Some cool-mist humidifiers work by flinging water at a vaporizer, but our favorite kind uses a piezoelectric transducer. These work by using high-frequency sound waves to pound the surface of the w… ...

With a 40-degree beam width, this Airmar transducer pairs its low-frequency range of 40 to 60 kHz with a medium-frequency range of 80 to 130 kHz. Your sounder will be tournament-ready with this ...
