Loudspeakers made out of graphene


Chemical vapor deposited graphene has been used to make an audio device where graphene coated PVDF film can emit sound waves in a range of frequencies with high sound pressure level and low harmonic distortion. This demonstrates that graphene has uses which one has to think. The results are published in Applied Physics Letters:
