A linear fluidic actuator comprising an upper actuation deformable surface suitable to induce a displacement in an actuation direction L and a wall delimiting an internal cavity wherein the shape of the actuator is a pillar; the wall, the cavity and the upper surface of a base form the lower part of said pillar, where h1 is the highest dimension of the internal cavity at rest according to the actuation direction L; a part forms the upper part of said pillar where the upper surface of said upper part is the upper actuation deformable surface, the bottom surface of said upper part closes the upper part of the cavity so as to form an upper surface of said cavity and where h2 is the distance at rest from the top of the upper surface of the internal cavity to the upper actuation deformable surface; the height ratio h1/h2 is comprised between 0.2 and 10; a fluidic inlet is provided and suitable for introducing a fluid in the internal cavity.
