Welcome !



Welcome to the CODE-team:

Due to technological progresses, micro and nano-technologies became major scientific, economic and strategic issues. They push away the frontiers for the manipulation and the characterization of small objects in various fields of applied sciences, as micro electronics component assembly, optics, biology etc… In biomedical field the study of genomes and the genetic manipulation have important therapeutic perspectives. Manipulation of very small organs such as small blood vessels allows new surgical approaches. In modern industry, the response to growing needs of complex assembled systems requires the availability of more and more accurate handling and assembly systems. Computer hard drives, mobile phones and telecommunication systems, are a few examples where product performance is directly related to the ability to manipulate very small components with high accuracy.


Micro and nano systems differ from conventional manipulation systems as they mainly use active materials and compliant structures. It also induces a growth in the complexity of the dynamic behavior of these micro-systems, in which surfacic forces are predominant compared to volumetric forces. Furthermore micro-systems are mainly multiphysic (coupling between thermal, magnetic, electric and mechanical effects), highly nonlinear and sometimes distributed parameters. Moreover sensors are very difficult to integrate and signal/noise ration becomes very high due to the very low amplitude of the signals (typical displacements: 1nm to 100μm and typical forces: 1nN to 10mN). In addition micro-nano systems are very sensitive to environmental variations (temperature, humidity…). Accurate and efficient manipulation at such scale remains an important and open problem.

The purpose of this thematic group is to develop new tools and theory for the control and the design of such microsystems working at micro or nano scales. The subjects treated in this group can be splitted into three main thematics:


- design and development of novel micromechatronic systems

- modeling and control of mechatronic and micromechatronic systems

- micro/nanorobotic tasks


 You can see more details on each of these three thematics by clicking the links in the right column of this website.
