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 ...

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 researchers to decide if ...

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 ...
