Les dispositifs d’isolation galvanique intégrés au sein des systèmes de commande d’interrupteurs de puissance doivent répondre à une demande accrue en performance, facilité d’intégration et efficacité énergétique. Les transducteurs ultrasonores capacitifs micro-usinés (cMUT : capacitive Micromachined Ultrasonic Transducer), capables d’émettre et de recevoir des ondes ultrasonores, semblent une alternative tout à fait nouvelle à la fonction d’isolation galvanique. Ces travaux de thèse ont pour objectif de démontrer la faisabilité d’un dispositif basé sur la technologie cMUT. Le principe de fonctionnement consiste à transmettre une information grâce à une communication par onde acoustique de volume entre deux réseaux de cMUT placés de part et...
