Description du projet
Un couplage magnétique innovant augmente les distances de transmission des dispositifs médicaux implantables
La connectivité sans fil connaît un essor fulgurant, reliant toujours plus de dispositifs à une vitesse, une sécurité et une fiabilité toujours plus grande. Les dispositifs médicaux implantables actifs (DMIA) dépendent également de la connectivité sans fil. Leur petite taille limite leur capacité de stockage des données et de l’énergie, ce qui implique des recharges et des transferts de données fréquents. La distance de transfert n’est actuellement que de quelques centimètres, ce qui est source d’inconfort, de stress et de résultats thérapeutiques sous-optimaux pour les patients. Avec le soutien du programme Actions Marie Skłodowska-Curie, le projet LongLinks-4-AIMDs entend décupler la distance de transfert possible grâce à une nouvelle approche de couplage magnétique à modulation temporelle, appelée modulation Q, pour une gestion intelligente de l’énergie. Cela pourrait permettre de commercialiser de nombreuses solutions médicales validées en laboratoire.
Objectif
Cardiovascular diseases, neuronal conditions, and metabolic disorders together cause 22 million deaths each year worldwide. Fortunately, those conditions can often be addressed through local sensing and treatments using for example active implantable medical systems (AIMDs) or transcutaneous bioelectronic devices. To be “invisible” to the patients, those devices should have the smallest volume possible, which means they pack only limited data and energy storage, relying on a wireless link to get recharged and to transfer data. Improvement in this link is urgently needed, as today’s poor transfer distance (few centimeters) leads to discomfort, cognitive overload, induces stress, reduces quality of life, and is associated with several suboptimal treatment outcomes. Because of this drawback, many medical solutions already validated in the lab cannot be implemented on patients.
My aim is to achieve a major advance in the way energy and data are transferred, and to gain an order of magnitude in the wireless transfer distance over existing technologies, through the development of a novel time-modulated magnetic coupling strategy.
The approach will consist of: (WP1) developing a “smart Q-modulation”, which operates in a manner similar to regenerative braking systems, where energy is temporary saved when the quality factor of the resonator has to be reduced for data transmission, and later reused to increase the quality factor for power transmission; (WP2) maintaining the system in energy-efficient operation against the body changing environment, and (WP3) guaranteeing a safe operation of the power transfer link.
By enabling new wireless scenarios, this project will enable a whole set of new medical devices to reach the market, providing autonomously and imperceptibly operation to the user, thus alleviating their cognitive burden. The technology will also be transferable to many other applications, such as industrial sensing, reinforcing the European leadership on the field
