The Zettl and Crommie research groups have previously published studies on graphene.
The study appears online in the Proceedings of the National Academy of Sciences.
The graphene loudspeakers and microphones operate from well below 20 hertz to over 500 kilohertz.
The structure of the speaker is almost same (to the old one), Zhou said.
One thing we improved was the production.
The other part is the circuit, which works as a loudspeaker.
They can also be used to correspond through objects, such as steel, that electromagnetic waves cant penetrate.
Zhou said he is positive about future research and all the potential applications.
There are a lot of different possibilities, he said.
