This particular kind of PCN has been shown, by another EPFL scientist, Tobias Kippenberg, to produce mechanical vibrations of different frequencies when it interacts with light.

Not exact matches

These materials are also used in everyday devices, such as loudspeakers, which rely on piezoelectrics to convert electrical signals to mechanical vibrations which create sound waves to produce the desired acoustic signal.

Nanoscale rods of the material wobble in response to mechanical stress — such as the vibrations produced by sound — and generate an electric field.

To find out how eggs can tell the difference between vibrations produced by, say, a harmless rainstorm and those produced by predators, Warkentin teamed up with Greg McDaniel, a mechanical engineer at Boston University, in the early 2000s.
