New design lets micro-clock resonators ring like a bell

You can't hear most of them, but the world is running on different kinds of mechanical oscillations. For example, inside the average electronic wristwatch is a sealed canister containing a 3 mm long quartz crystal resonator. ...

Scientists research effects of infrasonic vibrations in humans

It is known that the human body can generate mechanical vibrations at very low frequencies, so-called infrasonic waves. Such low-frequency vibrations are produced by physiological processes—heartbeats, respiratory movements, ...

Wideband wavelength conversion using cavity optomechanics

A team of researchers at the NIST Center for Nanoscale Science and Technology (CNST), the University of Maryland, and the California Institute of Technology have demonstrated optical wavelength conversion using interactions ...

New study strengthens olfactory vibration-sensing theory

(Phys.org)—A new study by a team of chemists in Greece has added credence to a theory that suggests that humans differentiate smells by sensing molecular vibrations, rather than through simple binding to receptors. In their ...
