Dynamics of Micro and Nanosystems (DMN)

In the last decades the field of microengineering and microelectromechanical systems (MEMS) has gone through a revolution. The accuracy of dimensioning mechanical structures has increased by a factor of more than 100, which has enabled integration of electromechanical devices onto a single chip. As a consequence, many consumer devices contain MEMS sensors and actuators like microphones, of which many are invisible to public. With the discovery of graphene and other 2D materials, on the other hand, it has become possible to control the thickness of materials at the atomic scale. At the same time developments in the semiconductor industry rapidly drive down the lateral dimensions of devices, with the 5 nm node being projected to arrive within 7 years. Although these developments are driven by the electronics industry, they also open new opportunities for novel mechanical devices. A size reduction by a factor of 10-100 is anticipated to lead to a second revolution in downscaling of mechanical devices from micro to nanoelectromechanical systems (NEMS), finally reaching a fundamental limit in engineering where dimensions become discretized and quantized at the single atom. Evidently, having an in-depth knowledge about the physics behind the performance of such micro and nano-mechanical components is of particular importance in development of the next generation of MEMS and NEMS devices. Dynamics of Micro and Nano Structures (DMNS) group therefore, is dedicated to the investigation of the mechanics of these components, particularly in dynamic motion. The research activities in the group can be divided into four research lines: (i) fundamentals of micro and nano mechanical systems; (ii) theoretical and experimental characterization; (iii) design and fabrication; (iv) development of new applications.

Education

 

The DMN group offers lectures for the Masters phase of the education. The group provides lectures on the fundamentals of dynamics as well as more advanced classes on topics including experimental mechanics, numerical methods and non-linear dynamics.

Research

The DMN group strives to pioneer new ideas and imagine better solutions in the fields of structural vibrations, non-linear dynamics and experimental dynamics.  Our research topics address open problems in the fields of non-linear dynamics and fluid-structure interaction of macro, micro and nano systems with innovations in experimental, theoretical and numerical investigation.
