Abstract:
(EN) The application describes MEMS transducers comprising a flexible membrane supported at a supporting edge relative to a substrate and further comprising one or more unbound edges. The shape of the unbound edge is selected so that the flexible membrane tends to bend along more than one bend axis in the region of the supporting edge.
(FR) L'invention concerne des transducteurs MEMS comprenant une membrane souple supportée au niveau d'un bord de support par rapport à un substrat et comprenant en outre un ou plusieurs bords non liés. La forme du bord non lié est choisie de telle sorte que la membrane flexible tend à se courber le long de plus d'un axe de courbure dans la région du bord de support.
