Adaptative Optics (AO) requires fast and precise wavefront control using deformable optical surface (DM) with a large number of actuators. Current commercial DM technologies are efficient but still suffer from limitations in their temporal bandwidth, dynamical range, size, number of actuators, fragility/fatigue, and non-linear effects that need to be overcome for future instruments. Moreover, these DMs have unperfect shape at rest and are costly. We aim to develop a new hybrid high-speed, lightweight, large and low-cost deformable-mirror technology.

As a biocompatible semiconductor composed of abundant elements, ZnO has received a huge interest for a wide variety of electronic, optoelectronic, chemical, and biological sensing applications. Thanks to its high PZ coefficients as a semiconductor, the integration of ZnO into PZ devices such as PZ nano-generators and/or pressure/strain sensors has extensively been considered in the last decade.

The project aims to develop ultra-light, self-correcting mirrors for use in the next generation of large optical telescopes and solar energy concentrators. Presently, the best mirrors have a density of about one-half a metric-ton per square-meter or more in order to provide the stiffness which is necessary to keep the optical shape under the variable conditions given by the changing gravity vector as the telescopes track a position on the sky, as well as to withstand variable wind conditions.

Evaluer rapidement l’état de santé d’une structure, sans attendre une maintenance programmée, constitue un enjeu considérable que ce soit pour les constructeurs, les compagnies aériennes et les équipes de maintenance.  Avec l’explosion  de  l’Industrie  4.0,  le  monde  de  la  maintenance  recherche  de  nouvelles  fonctions  de communication, d’interfaces et de capteurs.

Cardiac valve diseases are known to be an important public-health problem. Mitral Valve (MV) regurgitation (MR), also known as mitral insufficiency, is one of the most important of them. The regurgitation is either caused by a pathology of the valve itself (primary MR), or it is the consequence of a pathology of the myocardium (secondary MR).

Le projet ENHANCE (Innovative Training Network (ITN – réseau de formation innovant) a comme objectif de créer un programme structure interdisciplinaire pour former 13 jeunes doctorants qui effectueront leur recherche à la fois dans un consortium académique et industriel. Les sujets de recherche se focalisent sur la récupération d’énergie sans plomb pour les systèmes auto-alimentés, particulièrement dans le secteur automobile.
