Dr. Xavier Rottenberg , IMEC, Belgium

Electrostatic transducers and photonic devices for sensing applications

14.03.2017 (Tuesday) , 17:00 - 18:30
BIOTEC, seminar rooms E05/E06 , Tatzberg 47-49 , 01307 Dresden

The next seminar held in the framework of the lecture series Nanoscience and Nanotechnology offered by KU Leuven, Chalmers University of Technology Göteborg, Université Grenoble Alpes and TU Dresden will take place on March 14.


Microelectronics experiences since the early seventies a period of sustained run-away development. Researchers strive to keep up with and fulfill Moore's law by scaling transistors down thus cramming always more circuits, more computing power and more functions on a chip always smaller and faster. However, this More of Moore era is said to be coming to an end.
The past decades have seen a paradigm shift. Acknowledging the limitations of the scaling model for microelectronics, the emergence of novel technology drivers and appearance of new usage scenarios, e.g. low power, nomadism, health care and health monitoring, ..., researchers started exploring alternative technological paths. This defines the so-called More than Moore approach that departs from the one-technology-fits-all approach and aims at developing a plurality of diverse ad-hoc technologies and according interfacing solutions. MEMS (micromachining/microsystems) is one of these technologies that enables the development of novel transducers for always smarter systems.

This presentation introduces the basics of electrostatic MEMS devices, i.e. their actuation and operation as sensor, their functions through some sensor examples and their main reliability issues. Finally, this presentation will sketch the main characteristics of novel emerging photonic technologies for (bio-)sensing and imaging applications.

About the speaker:

Xavier obtained the M.S. degree in Phys. Eng. and the DEA in Theoretical Physics from the “Université Libre de Bruxelles” in 1998 and 1999, respectively. He obtained in 2008 his PhD degree in Elec. Eng. from the KULeuven. He worked one year at the Royal Meteorological Institute of Belgium in the field of remote sensing from space. He has been at IMEC Leuven, since 2000, where he contributes to research in the field of RF, RF-MEMS, photonics and microsystems modelization/integration. In these fields, he has co-authored over 60 peer-reviewed papers and has been issued various patents. He currently leads at IMEC the Microsystems Design and Modeling team working among other topics on photonics, sensors, acoustics, M/NEMS, etc.
