Abstract
The invention relates to an electromechanical actuator with increased deformation, including, on the one hand, at least one drive element connected to a source of AC voltage so as to produce a deformation of the drive element and, on the other hand, a plate configured for amplifying the amplitude of the vibration that the drive element must transmit to a substrate to be actuated. A first face of the plate is rigidly fixed to the drive element and a second face of the plate, opposite to the first face, is fixed by means of an actuation lug to the substrate to be actuated.
