SUMMARY:Chaotic regime in micromechanics: generation\, characterization and applications
DESCRIPTION:Martedì 9 settembre si terrà un seminario presso l’aula Fassò (Edificio 4A) dalle ore 16:30 dal titolo “Chaotic regime in micromechanics: generation\, characterization and applications”. \nIl seminario sarà tenuto dal Dr. Martial Defoort\, University of Grenoble Alpes\, CNRS\, Grenoble INP\, TIMA\, Grenoble. \nSarà anche possibile seguire il seminario da remoto tramite il seguente link: https://politecnicomilano.webex.com/meet/valentina.zega \n\nAbstract\n\nMicromechanical systems have become essential in the development of the latest technologies\, from cars to smartphones to medical implants. Due to their size\, these devices offer fast response times\, low power consumption\, and high sensitivity\, creating a buzz in both academic and industrial research. This ambivalence creates a direct bridge between fundamental research and engineering science\, exploiting complex behaviors for specific applications. This is the case for nonlinear phenomena\, often considered undesirable\, but which also offer new perspectives and give rise to disruptive applications.\n\nThis presentation will focus on one nonlinear phenomenon in particular: the chaotic regime in mechanical microresonators. After a general introduction to chaos and its generation in microtechnologies\, a second part will be dedicated to the experimental characterization of this regime within a microelectromechanical system (MEMS) in order to assess the richness of the chaos thus generated. The final part of this presentation will discuss the various possible applications\, from improving transducer performance to secure communications. \n\n\n—\n\nSpeaker’s bio\n\nMartial Defoort completed his doctoral studies in fundamental research at Intitut Néel\, Grenoble\, in 2014 on nonlinear micro/nanomechanics. He then pursued postdoctoral research at the University of California\, Davis\, focusing on applied research and in particular synchronization of MEMS gyroscopes. Coming back to France\, he obtained a postdoctoral position at CEA-Léti\, where he explored NEMS-arrays for mass spectrometry applications. In 2020\, he joined the laboratory Techniques de l’Informatique et de la Microélectronique pour l’Architecture de systèmes intégrés (TIMA) in Grenoble as a CNRS research scientist\, specializing in nonlinear physics\, MEMS and chaos-based applications. In particular\, he focuses his research on how to leverage chaos properties in MEMS for sensing and security applications.

SUMMARY:Microfluidic chip with bioimpedance sensor to study blood rheology
DESCRIPTION:Giovedì 25 settembre si terrà un seminario presso l’aula Grandori (Edificio 4 – piano seminterrato) alle ore 14:30 dal titolo “Microfluidic chip with bioimpedance sensor to study blood rheology”. \nIl seminario sarà tenuto dal Prof. Olivier Francais\, ESIEE Paris. \nAbstract \nMicrofluidic chips are promising tools for studying blood rheology in the context of diseases such as sickle cell anemia. These miniaturized devices can mimic the geometry and environment of blood capillaries\, allowing precise control of flow and characterization of red blood cells. The integration of electrodes into these chips allows the electrical impedance of blood to be measured\, providing a means of quantifying red blood cell properties such as deformability and stiffness. This approach\, combining microfluidics and bioimpedance\, paves the way for new methods of diagnosis\, treatment monitoring\, and therapeutic molecule screening by providing essential information on the behavior of blood cells at the single red blood cell level. \nSpeaker’s bio\n\nOlivier FRANCAIS is a full Professor at ESIEE Paris\, engineering school member of Université Gustave Eiffel (France)\, with the position of academic Dean. He is member of the “Health\, Energy\, Environment” department where he teaches Applied Physics\, Instrumentation and Micro-electronic Technologies for Lab on a Chip.\nHe conducts his research at the ESYCOM laboratory (CNRS UMR 9007) in the field of sensors for Health and Lab-On-a-Chip. He is more specifically interested in the development of interfaces for analysis of biological species within microfluidic environment\, taking benefits of their dielectric properties.\nHe is an expert concerning electric parameters extraction within microfluidic devices from bio-impedance measurement at low frequency range (Hz to several MHz) and in dielectric characterisation of biological materials at higher frequency (up to several GHz). During his career\, he has developed several technology lines in the field on microfluidics where he has acquired an international expertise. He masters the clean room facilities in order to conduct research and innovation for Lab On a Chip applications.

SUMMARY:Unveiling piezo-mems dynamics with interferometric eyes
DESCRIPTION:Giovedì 25 settembre si terrà un seminario presso l’aula Grandori (Edificio 4 – piano seminterrato) alle ore 15:30 dal titolo “Unveiling piezo-mems dynamics with interferometric eyes”. \nIl seminario sarà tenuto dalla Prof.ssa Sabina Merlo\, Università degli Studi di Pavia. \nAbstract\n\nPiezo-MEMS speakers based on the inverse piezo-electric effect are becoming increasingly attractive thanks to their low power consumption and are good candidates for miniaturized devices for smart-phones and in-ear audio systems. Piezo-actuated tunable microlenses are also of great interest in various miniaturized systems. In this seminar\, I will illustrate the functionality of laser diode feedback interferometry\, or self-mixing interferometry\, for analyzing the out-of-plane vibration performance of a commercial piezo-MEMS speaker\, showing the advantages with respect to a classical Michelson scheme. Characterization of the quasi-static behavior of a tunable microlens by means of low-coherence interferometry will be illustrated\, as another example of application of spot-optical techniques for MEMS testing.\n\nSpeaker’s bio\nSabina Merlo received in 1987 the master’s degree and in 1991 the Ph.D. degree\, both in electronic engineering\, from the University of Pavia. She also received the M.S.E. degree in bioengineering from the University of Washington\, Seattle\, USA\, in 1989\, thanks to a Rotary Foundation Graduate Scholarship. Assistant Professor since 1993 and Associate Professor since 2001\, she is now Full Professor of Electrical and electronic measurements since 2018 at the Department of Electrical\, Computer and Biomedical Engineering\, University of Pavia.\nShe is president of the Teaching council of Information Engineering at the University of Pavia and Vice-President of the “Distretto della Microelettronica Pavese” recognized as Ecosystem for Microelectronics of the Italian Lombardy region.\nHer research interests include applications of photonics techniques for the measurement of physical and chemical parameters\, optical testing of MEMS/MOEMS and microfluidic devices\, interferometry\, optical chemical sensing and other photonic applications. She has collaborated with STMicroelectronics on MEMS/MOEMS since the very beginning of the company activity in this field (2000). She holds four patents and is the author of more than 200 publications in journals\, books\, and conference proceedings. She was an Associate Editor of IEEE/ASME JMEMS until 2024\, she is now an Associate Editor of MDPI Sensors and MDPI Micromachines.

SUMMARY:Quando Piove Troppo: Capire le Alluvioni in un Mondo che Cambia
DESCRIPTION:Giovedì 25 settembre si terrà una Lectio Magistralis presso l’aula Magna (Edificio 1) dalle ore 16:30 alle 18:00 dal titolo “Quando Piove Troppo: Capire le Alluvioni in un Mondo che Cambia”. \nLa Lectio Magistralis sarà tenuta dal Prof. Guenter Bloeschl\, Technical University of Wien & Università degli Studi di Bologna\, vincitore dello Stockholm Water Price 2025. \nAbstract \nLe alluvioni sono tra i disastri naturali più frequenti e impattanti. Ma quali sono davvero le cause? È solo colpa del cambiamento climatico? O ci sono altri fattori\, come l’urbanizzazione\, le opere idrauliche e l’uso del suolo? \nQuesto seminario ci guiderà in un viaggio attraverso le vere dinamiche che stanno dietro alle piene fluviali. Scopriremo come i cambiamenti nel territorio e le scelte umane abbiano modificato il modo in cui l’acqua si comporta nei nostri paesaggi. Un’occasione per guardare oltre le semplificazioni e affrontare la complessità di un problema che riguarda tutti.
