Abstract
Device including a membrane and a support defining a cavity containing a fluid, where the membrane includes an anchoring area to the support, a central area able to be deformed following a displacement of fluid and an actuation area between the anchoring and central areas, and means of actuation to apply stress to the membrane in the actuation area and cause a displacement of the fluid to the central area following an actuation. The cavity includes a main chamber in the central area and a peripheral chamber in the actuation area communicating with the main chamber. The peripheral chamber includes at least one forced flow structure favoring the flow of at least a part of the fluid from the peripheral chamber to the main chamber or vice versa following the actuation. A given forced flow structure has no attachment both to the support and to the membrane.
