Following on from their discovery of graphene “speakers”, scientists in China have done more detailed study of the amplitude and frequency of the sound at different distances and angles, and the temperature dependence of the sound frequency. The authors are optimistic about the applications of these devices in multimedia and consumer electronics as well as biological and medical devices.
