vibrations

I feel the same vibrations in my palm as I did when I was holding the akrafena.

Similar properties could be used to build finely tuned sensors that detect extremely small vibrations or pressure shifts, or to develop adjustable light sources for advanced displays and imaging systems.

In most superconductors, electrons pair up due to vibrations in the surrounding atomic lattice, which gently push them together.

In most saltwater species, vibrations reach the inner ear only weakly, which limits hearing to low frequencies below about 200 Hertz.

They wait motionless for surface vibrations, darting out only when prey strays within reach.
