Graphene drums

Scientists from the TU Delft Kavli Institute have been able to make extremely small drums made of graphene. Due to the extremely low weight of graphene, the researchers were able to use small pieces in a way that is similar to the drumhead on a drum. They then ‘played’ the drum using microwave radiation, listened to the resulting ‘nano-sounds’ and examined how exactly the graphene layer moved. Thanks to their special mechanical properties, graphene drums could be used as sensors, in cell phones for example, or memory chips in future quantum computers.
