Many of today's consumer electronics rely on microscopic machines. These tiny devices are found in smart-phone motion sensors, inkjet printheads, and the switches that activate some display pixels, to name just a few components.

Shrinking these electromechanical machines down to the nanoscale would enable new devices, such as extremely sensitive chemical sensors, incredibly precise accelerometers, and super-fast integrated circuit switches. In an important step toward this goal, researchers at Cornell University have made large arrays of nanoscale resonators using graphene.
