A movement amplifying actuation device may include two piezoelectric beams, one beam being attached at a fixed point, and a hinge connecting a first beam and a second beam between them. Each hinge may include a first flexible portion connected to the first beam, a second flexible portion connected to the second beam, a first rigid portion connecting the first and second flexible portions, a second rigid portion capable of being positioned against a fixed point, and a third flexible portion connecting the second beam to the second rigid portion at a pivot point of the second beam such that the assembly formed by the second rigid portion and the second beam forms a lever around the pivot point. The flexible and rigid portions may form a single piece.
