Abstract
Described are micro electrostatic transducers and methods of making such devices. The micro electrostatic transducer is an integrated component transducing device fabricated from materials allowing for low cost, high volume manufacturing. The device includes a sheet of graphene forming the diaphragm with two electrode layers above and below the diaphragm to introduce the audio signal.
