Acoustic wave based and innovative Detection Microsystems

 

The MDA team develops smart acoustic / electromagnetic platforms for fast detection of chemical or biological species, as well as characterization of thin solid films or complex fluids at high frequencies. Wireless transmission of data and of micro-energy is also investigated and a sustainable approach is fostered. Health, Energy and Environment fields are particularly targeted with numerous potential benefits in various areas of activity.

Presentation of the waves research activities of the MDA team

 

Our research works especially involve the study of waves propagation, including emission / reception, and dynamical interaction mechanisms with solid, liquid or gaseous media. The realization of ultra-sensitive and reliable microsensors together with processing electronics is an overarching goal, towards embedded and communicating systems adapted to a digital environment. All projects are carried out in close collaboration within a multidisciplinary team (electronics, microtechnology, chemistry, biology, etc.) gathering local/national/international academic and/or industrial partners.

We develop platforms for fast dedicated detection of chemical or biological species, as well as for characterization of thin solid films or complex fluids at high frequencies. Health, Energy and Environment fields are particularly targeted with numerous potential benefits in various areas of activity

Résumé en français

L’équipe MDA (Microsystèmes de Détection Acoustique et alternatives) développe des plateformes acoustiques/électromagnétiques intelligentes pour la détection rapide d’espèces chimiques ou biologiques, ainsi que pour la caractérisation de films minces ou de fluides complexes à haute fréquence. La transmission sans fil de données et de micro-énergie est également étudiée et une approche durable est encouragée. Les domaines de la santé, de l’énergie et de l’environnement sont particulièrement visés avec de nombreuses retombées potentielles dans divers secteurs d’activité.

 

Nos travaux de recherche portent notamment sur l’étude de la propagation des ondes, y compris l’émission/réception, et les mécanismes d’interaction dynamique avec les milieux solides, liquides ou gazeux. La réalisation de micro-capteurs ultra-sensibles et fiables associés à une électronique de traitement est un objectif primordial, vers des systèmes embarqués et communicants adaptés à un environnement numérique. Tous les projets sont menés en étroite collaboration au sein d’équipes pluridisciplinaires (électronique, microtechnologies, chimie, biologie, etc.) regroupant des partenaires académiques et/ou industriels locaux/nationaux/internationaux.
