Graphene earphone

The first prototype of a graphene earphone able to ensure superior performance compared to devices already on the marketplace.

Two young researchers at the University of California Berkeley have created an audio device capable of ensuring high-quality sonic performance thanks to the use of graphene. The prototype is formed by a thin graphene membrane sandwiched between two electrodes that generate an electric field. When the electric field oscillates, the graphene sheet vibrates producing sound.

The possibility to create the membrane with the “material of the future” allows to overcome the limitations of the devices already present in the marketplace. In fact, the new membrane is very thin and light (just 5 mm in diameter and 30 nanometers thick). Thanks to these characteristics, it is able to originate an almost perfect sound.
