Title (EN) MICROMACHINED ULTRASONIC TRANSDUCERS WITH A SLOTTED MEMBRANE STRUCTURE
(FR) TRANSDUCTEURS ULTRASONIQUES MICRO-USINÉS AYANT UNE STRUCTURE DE MEMBRANE À FENTES
Abstract: front page image
(EN)A piezoelectric micromachined ultrasonic transducer (PMUT) device includes a substrate having an opening therethrough and a membrane attached to the substrate over the opening. A portion of the membrane that overlies the opening is divided into a plurality of cantilevers that are mechanically coupled so that the cantilevers resonate at a common frequency.
(FR)La présente invention concerne un transducteur ultrasonique micro-usiné piézoélectrique (PMUT) qui comporte un substrat, traversé par une ouverture, et une membrane attachée au substrat au-dessus de l’ouverture. Une partie de la membrane qui repose au-dessus de l’ouverture est divisée en une pluralité d’extensions qui sont couplées mécaniquement de sorte que les extensions résonnent à une fréquence commune.
