PhD 1: Ouari Mondher (L2EP)
Mondher hold an Engineering Degree in control system from the National Polytechnic School of Algiers and a master’s degree in control systems and Electrical Engineering from University of Poitiers. He studied advanced control theories and applied them to Electrical systems. During his internship at LCOMS laboratory in Metz, He worked on minimizing torque ripple of SynRm.
Real-time control and implementation of a tunable tactile interface
Mondher’s main goal in this project is to develop a methodology to control of multimodal vibrations on surfaces of a metamaterial, and to implement them. As part of this position, and of the corresponding Ph.D. studies planned for this project, he will contribute to develop tunable prototypes that can generate a click sensation as haptic feedback.
PhD 2: Favrot Jeanne (LGF)
Coming from a training combining applied arts, product design and model making, Jeanne moved to mechanics. She worked in a design office for the design of engines and gearboxes at Renault for several years. She then resumed her studies at UTC in user experience design (UXD), then did a doctoral thesis at the Ecole des Mines de Saint-Etienne.
Her work focuses on the sensory evaluation of materials and systems for tactile interfaces. In a context where touch technologies are becoming part of our daily lives, physical controls such as buttons or switches tend to disappear in favor of touch interfaces. The challenge is to make these surfaces more alive with haptic interactions better thought out to meet the challenges of digitalization. Faced with this observation, her work proposes to study, upstream of the design chain, physical and tactile controls in order to determine their sensory characteristics with the aim of proposing perceptual specifications for future tactile interfaces. Enriched with a field of micro-gestures calling for specific actions, this will make it possible to design future tactile interfaces.
Post Doc 1: Massaï Hatoumva (IEMN)
Holder of a Ph.D. in Physics of Complex Systems, with a mayor in Sound and Ultrasonic Acoustics, from the University of Maroua, Cameroon in collaboration with LOMC of the University of Le Havre Normandie, I am interested in the tunability of active acoustic metamaterials especially phononic crystals. My research work is a contribution to the design of
“smart materials”, in particular piezoelectric/elastic phononic crystals, whose mechanical properties can be modulated in order to control and manipulate in real time the frequency range of elastic wave propagation through their structure.
Designing of back layers for tactile stimulators
To accommodate the use of metamaterials for haptic feedback purpose to several types of surface, in this project, we contribute to design and put in place tunable back layers to the
surface in order to modulate the ultrasonic behaviour for the tactile simulators. To overcome this challenge, tunable elements should be inserted inside the layers forming the metamaterial.
The key idea here is to add gradually piezoelectric inclusions and connect them to an especial electronic device. After carried out tunability and versatility studies in simulation, we will then participate to the practical implementation of the proposed technique.
