STAGE de fin d'étude - Simulations numériques pour la conception de capteurs EMAT - H/F
En contrôle par ultrasons, les technologies de génération d’ondes élastiques dans la matière peuvent se scinder en 2 catégories principales : les capteurs avec couplage (capteurs piézoélectriques) et les capteurs sans couplage. Parmi ces derniers, on peut mentionner les pointes sèches, les ultrasons laser ou encore les EMAT (ElectroMagnetic Acoustic Transducer). Les EMAT présentent plusieurs...

Ultra-low frequency wireless power transmission for sensor node charging
Wireless power transfer (WPT) technologies are rapidly expanding, particularly for wireless charging of everyday electronic devices and for powering wireless communicating sensor nodes. However, their transmission ranges remain limited, and the high operating frequencies typically used prevent energy transfer in the presence of, or through, conductive media (such as metallic barriers or seawater). This constraint...

Distributed multimodal learning for cooperative acoustic source localization and classification
In many complex environments, such as industrial sites, disaster-stricken buildings, or public spaces, it is necessary to automatically detect and localize sound events (falls, alarms, voices, mechanical failures). Mobile platforms equipped with cameras and microphones represent a promising solution, but a single platform remains limited: its microphone array provides an approximate direction towards the source...
