More Information
Summary: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.
