Drum beats from a one atom thick graphite membrane
Researchers demonstrate the ability to electrically manipulate the vibrations of a drum, of nanometer scale thickness, a million times smaller than that of human hair. These drums vibrate a whopping 100 million times a second — which cannot be heard by the ear but can be sensed using small circuits. This can be used to make new kinds of mass sensors. Also, new aspects of fundamental physics could be probed in the future.
