Mini-review: Novel Graphene-based Acoustic Devices
Abstrak
Graphene has extremely high electron mobility, good thermal conductivity, and excellent acoustic properties, making it an ideal acoustic material. Currently, there are three main types of graphene used in acoustic devices: graphene films prepared by chemical vapor deposition (CVD), vertical graphene (VGr) and laser-induced graphene (LIG). Among them, Graphene prepared by CVD is lighter, thinner and more sensitive; VGr is grown by the microwave plasma chemical vapor deposition (MPCVD) method, which has higher ductility and sound pressure level (SPL); LIG has the advantages of low cost, simple preparation and no biological toxicity. This paper introduces the applications of these three materials in the direction of acoustic devices. In addition to the simple acoustic-electrical conversion application, an artificial throat with the intelligent recognition function is introduced. These different types of graphene acoustic devices have greatly promoted the application of graphene in the field of acoustics.
