Paul Thibado from the University of Arkansas and his students observed the movement of graphene under a scanning tunneling microscope (STM). At incredibly small scales, they found there was not only Brownian motion but also larger movements of the graphene sheet itself, with the atoms moving together. Using a graphene sheet that measured 10 microns across, the researchers said they were able to produce about 10 microwatts of power continuously, without any loss.
In the video, Thibado explained how this motion could be used to replace batteries that we use today. Creating something called the Vibration Energy Harvester (VEH), he showed how a negatively charged sheet of graphene between two electrodes could produce an alternating current.
