    摘要: The The invention relates to a touch interface comprising a contact surface and means for vibrating the contact surface, said means being provided to generate standing waves in said surface. The contact surface includes at least one transparent portion forming a surface for seeing through the touch interface, and the vibration generating means include at least one rigid piezoelectric layer that is rigidly connected to the contact surface and disposed on the periphery of the transparent portion. The interface is characterized in that the at least one piezoelectric layer is disposed in a plane that is not parallel to the contact surface. The invention also relates to a display screen using such an interface, and to an electric appliance using such a display screen.

    摘要: A device for measuring an acceleration includes a vibrating accelerometer including: a semiconductor substrate forming a fixed frame of the accelerometer; a test weight of the same material as the substrate and connected to the fixed frame, movable translationally along at least one sensing axis of the vibrating accelerometer; a guide of the same material as the substrate, connected to the fixed frame and test weight, guiding the test weight in the direction of the sensing axis; a layer made of a piezoelectric semiconductor deposited on the substrate, the layer being tensilely prestrained; a resonator in the layer connected to the fixed frame, the resonator subjected to tension or compression in the direction of the sensing axis; and at least one transducer connected to the resonator, able to actuate the resonator, to keep the resonator oscillating and/or to detect an electrical signal generated by the resonator.
