Abstract (en)
[origin: WO2020141264A1] The invention relates to an electromechanical actuator with increased deformation, having at least one driving element (21) connected to an alternating voltage source so as to bring about a deformation of said driving element (21), and also a plate (22) configured to increase the amplitude of the vibration that the driving element (21) is intended to transmit to a support (40) to be actuated, characterized in that a first face of the plate (22) is fixed rigidly to the driving element (21), and in that a second face of the plate (22), on the opposite side from the first face, is fixed by an actuating stud (23) to the support (40) to be actuated.
