  • Publication number: 20240034616
    Abstract: The invention relates to an electromechanical microsystem comprising an electromechanical transducer, a deformable membrane and a cavity hermetically containing a deformable medium, preserving a constant volume under the action of an external pressure change. The deformable membrane forms a wall of the cavity and has at least one free zone being deformed. The electromechanical transducer is configured, such that its movement is a function of said external pressure change, and conversely. The free zone engages with an external member, such that its deformation induces, or is induced by, a movement of the external member. The electromechanical microsystem is thus capable of moving the external member or of capturing a movement of this member.

  • Patent number: 11692459
    Abstract: A method for manufacturing a turbine engine part in which a first rough casting element includes a first face and a second face opposite to each other is assembled by the second face on an orifice which has a second element of the part. The method includes machining a through-cavity in the first element which opens at the first face and from the second face of the first element and machining the first face of the first element so as to form an area suitable for ensuring the attachment of a conduit on the first element. The machining of the cavity and of the first face is achieved by using a machining reference frame based on the second element.

  • Publication number: 20220380207
    Abstract: An electromechanical microsystem including two electromechanical transducers, a first deformable diaphragm and a cavity hermetically containing a deformable medium keeping a constant volume under the action of a change in the external pressure. The first diaphragm forms at least one portion of a first wall of the cavity and has a freely deformable area. The free area cooperates with an external member so that its deformation induces, or is induced by, a movement of the external member. The electromechanical transducers are configured so that a first electromechanical transducer forms a portion of the first wall of the cavity, and a second electromechanical transducer forms at least one portion of the wall opposite to the first wall of the cavity.

  • Publication number: 20220380205
    Abstract: An electromechanical microsystem including an electromechanical transducer, a deformable diaphragm and a cavity hermetically containing a deformable medium keeping a constant volume under the action of an external pressure change. The deformable diaphragm forms a wall of the cavity and has at least one free area so as to be elastically deformed. The electromechanical transducer is configured so that its movement depends on the change in the external pressure, and vice versa. The free area cooperates with an external member so that its deformation induces, or is induced by, a movement of the external member. Thus, the electromechanical microsystem is adapted to displace the external member or to detect a movement of this member, the electromechanical microsystem includes at least one pin, configured to bear on a peripheral portion of the free area so that a deformation of the free rea causes an inclination of the pin.

  • Publication number: 20220380206
    Abstract: An electromechanical microsystem including an electromechanical transducer, a deformable diaphragm, a first cavity hermetically containing a deformable medium keeping a substantially constant volume under the action of an external pressure change and a second cavity. The deformable diaphragm forms a wall of the cavity and has at least one area freely deformable elastically. The free area also forms a wall of the second cavity. The electromechanical transducer is configured so that its movement depends on the external pressure change, and vice versa. A change in the external pressure in the first cavity induces a variation of the volume of the second cavity, or vice versa. Thus, the proposed electromechanical microsystem enables gripping of an object obstructing the opening of the second cavity and forms a microbarometer capable of converting at least one ambient pressure change into an electrical signal.

  • Publication number: 20220197014
    Abstract: The invention relates to an electromechanical microsystem 1 including at least two electromechanical transducers 11 and 11a, a deformable diaphragm 12 and a cavity 13 hermetically containing a deformable medium 14 maintaining a constant volume under the action of an external pressure change. The deformable diaphragm forms a cavity wall and has at least one deformable free area 121. The electromechanical transducers are configured so that their movement is a function of the said external pressure change, and conversely, and be in the same direction for at least two of them. The electromechanical microsystem 1 is thus able to deform the free area of the diaphragm in step mode towards the inside or outside of the cavity.

  • Publication number: 20220197013
    Abstract: The invention relates to an electromechanical microsystem 1 including at least two electromechanical transducers 11 a and 11 b, a deformable diaphragm 12 and a cavity 13 hermetically containing a deformable medium 14 maintaining a constant volume under the action of an external pressure change. The deformable diaphragm forms a cavity wall and has at least one elastically deformable free area 121. The electromechanical transducers are configured so that their movement is a function of the said external pressure change, and vice versa, and so that two of them have opposing movements relative to each other. The free area cooperates with an external member 2 so that its deformation causes, or is caused by, a movement of the external member. The electromechanical microsystem is thus able to move the external member and/or sense a movement of this member, alternately towards the inside or outside of the cavity.
