<p>A linear fluidic actuator comprising an upper actuation deformable surface (240) suitable to induce a displacement in an actuation direction L and a wall (220) delimiting an internal cavity (210) wherein:
- the shape of the actuator is a pillar (205);
- the wall (220), the cavity (210) and the upper surface of a base (300) form the lower part of said pillar (205), where h1 is the highest dimension of the internal cavity (210) at rest according to the actuation direction L;
- a part (230) forms the upper part of said pillar (205) where the upper surface of said upper part (230) is the upper actuation deformable surface (240), the bottom surface of said upper part (230) closes the upper part of the cavity (210) so as to form an upper surface (215, 216, 217) of said cavity and where h2 is the distance at rest from the top of the upper surface (215, 216, 217) of the internal cavity to the upper actuation deformable surface (240);
- 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 (210).</p> |
