For\ndecades microelectromechanical systems (MEMS) have been the basis for new\ninnovations in sensor and medical technology. Now these systems are moving to\nthe next level: nano-electromechanical systems, or NEMS. Thanks to its extraordinary mechanical\nstrength, its atomic-thickness, and its excellent conducting properties,\ngraphene is one of the most promising materials for a breathtaking array of\napplications in nano-electromechanical systems. <\/p>\n\n\n\n
\u201cWe can\nscale down components because of the material\u2019s atomic-scale thickness, and it\nhas great electrical and mechanical properties,\u201d says Xuge Fan, a researcher in\nthe Department for Micro and Nanosystems at KTH. \u201cWe created a piezoresistive\nNEMS accelerometer that is dramatically smaller than any MEMS accelerometers\navailable today, but retains the sensitivity these systems require.\u201d<\/p>\n\n\n\n
The future\nfor such small accelerometers is promising, says Fan, who compares advances in\nnanotechnology to the evolution of smaller and smaller computers. \u201cThis could eventually\nbenefit mobile phones for navigation, mobile games and pedometers, as well as\nmonitoring systems for heart disease and motion-capture wearables that can\nmonitor even the slightest movements of the human body,\u201d he says. “In addition, these\nNEMS transducers can be used as a system to characterize the mechanical and\nelectromechanical properties of graphene itself.”<\/p>\n\n\n\n
Max Lemme,\nprofessor at RWTH and Managing Director at AMO GmbH, is\nexcited about the results: “Our collaboration with KTH over the years has\nalready shown the potential of graphene membranes for pressure and Hall sensors\nand microphones. Now we have added accelerometers to the mix. This makes me\nhopeful to see the material on the market in some years. For this, we are\nworking on industry-compatible manufacturing and integration techniques.” <\/p>\n\n\n\n
This type of research is a good example of the activities pursued at the Aachen Graphene and 2D Material Center, Lemme says. “What is very characteristic of research on graphene and two-dimensional materials is the close feedback-loop between basic and applied research. We try to turn into real-life applications properties that have only recently been discovered, and this makes it for me all the more exciting”. <\/p>\n\n\n\n
