Abstract

Engineered nonlinearities have been shown to play an important role in increasing the efficiency of energy harvesting devices. Macroscopic prototypes using this approach have been demonstrated recently [F. Cottone, H. Vocca, and L. Gammaitoni, Phys. Rev. Lett.PRLTAO0031-900710.1103/PhysRevLett.102.080601 102, 080601 (2009).] Here, in order to implement such a scheme at the nanoscale, we propose a simple device which is based on strained nanostructured graphene and discuss how it can respond to many energy sources that, although having a low intensity, are freely available, such as ambient vibrations or thermal noise. We discuss in some detail the case of thermal fluctuations harvesting in the steady-state nonequilibrium regime and of ambient vibrations. © 2011 American Physical Society.
