We demonstrate that the cell wall of living Saccharomyces cerevisiae (baker's yeast) exhibits local temperature-dependent nanomechanical motion at characteristic frequencies. The periodic motions in the range of 0.8 to 1.6 kHz with amplitudes of 3 nm were measured using the cantilever of an atomic force microscope (AFM). Exposure of the cells to a metabolic inhibitor causes the periodic motion to cease. From the strong frequency dependence on temperature, we derive an activation energy of 58 kJ/mol, which is consistent with the cell's metabolism involving molecular motors such as kinesin, dynein, and myosin. The magnitude of the forces observed (10 nN) suggests concerted nanomechanical activity is operative in the cell.

Abstract
Nanoelectromechanical systems, NEMS, have been investigated in the last decade with a special emphasis in the detection of fundamental magnitudes. NEMS, as a natural consequence of the MEMS downscaling, inherit their multi-domain response with a dramatic improvement in terms of sensitivity, resolution and energy consumption. The unique miniaturization and low-consumption opportunities that offer resonant NEMS have also been studied in the field of integrated radio communications. In this lecture we will analyze the potential possibilities that NEMS also offer in the field of energy scavenging from ambient sources. Modeling and design issues, as well as their link to top-down and bottom-up technologies and fabrication processes will be introduced. A special emphasis will be dedicated to the linear resonance and non-linear mechanical characteristics of NEMS, as a key point in terms of energy efficiency in the transduction process. A complete self-powered system will be described, considering the transduction-management-storage chain of the energy, as well as the application subsystem that uses the harvested energy. NEMS role in the power management and storage blocs will also be introduced. Finally, the complementarity of NEMS based energy harvesters with ongoing sensing and communications NEMS based applications will be envisaged.
