Abstract

Ce dispositif comprend un module de récupération d'énergie avec un ensemble pendulaire formé d'une lame piézoélectrique (26) élastiquement déformable associée à une masse inertielle (30). Une pièce multifonction (100) comprend un évidement axial traversant (104) avec des surfaces d'appui internes (106) en regard de faces externes respectives de la lame (26). Ces surfaces d'appui présentent un écartement transversal croissant, tel qu'au cours d'un cycle d'oscillation la lame vient en contact avec l'une des surfaces d'appui, réduisant ainsi la longueur libre de la lame au fur et à mesure de la flexion de cette dernière. La pièce multifonction permet également de rationaliser la fabrication et l'assemblage de la capsule, avec intégration poussée des composants internes de l'implant.
