Title (EN) DEVICE FOR CONVERTING MECHANICAL ENERGY INTO ELECTRIC ENERGY USING AT LEAST ONE PIEZOELECTRIC TRANSDUCER
(FR) DISPOSITIF DE CONVERSION D'ENERGIE MECANIQUE EN ENERGIE ELECTRIQUE A L'AIDE D'AU MOINS UN TRANSDUCTEUR PIEZOELECTRIQUE
Abstract:
(EN) The invention relates to a device for converting mechanical energy into electric energy, comprising at least one conversion cell (C) comprising at least one percussion mechanism (6) including one deformable member (7), having at least two opposite anchoring points, rigidly connected in a central area of a percussion member (8), and one or more piezoelectric transducers (10) coupled to an acoustic resonator (9). The deformable member (7) includes at least one stable position in which the percussion member (8) is remote from the acoustic resonator (9), the percussion mechanism (6) and the acoustic resonator (9) being arranged so that when a force exceeding a threshold is applied onto the deformable member (7), the latter leaves the stable position by deformation so that the percussion member (8) hits the acoustic resonator (9) so that it resonates and excites the piezoelectric transducers (10) and so that the energy generated by the force is converted by the piezoelectric transducers.
(FR) Dispositif de conversion d'énergie mécanique en énergie électrique formé d'au moins une cellule de conversion (C) comportant au moins un mécanisme de percussion (6) incluant un élément déformable (7), ayant au moins deux points d'ancrage opposés, solidaire dans une zone centrale d'un élément de percussion (8) et un ou plusieurs transducteurs piézoélectriques (10) couplés à un résonateur acoustique (9). L'élément déformable (7) possède au moins une position stable dans laquelle l'élément de percussion (8) est éloigné du résonateur acoustique (9), le mécanisme de percussion (6) et le résonateur acoustique (9) étant agencés de manière que lorsqu'une force supérieure à un seuil est appliquée sur l'élément déformable (7), il quitte sa position stable en se déformant afin que l'élément de percussion (8) vienne percuter le résonateur acoustique (9) pour qu'il entre en résonance et excite les transducteurs piézoélectriques (10) de sorte que l'énergie induite par la force soit convertie par les transducteurs piézoélectriques.
