A device, which is autonomous or which can be associated with another structure, for propulsion in a liquid environment, is described. The device has a bladder body made of a soft material, developing along and around a central longitudinal axis, defining an internal chamber between a dorsal wall and a ventral wall; in the bladder body, an inlet opening and an outlet opening of a liquid in and out of the chamber, arranged at a longitudinal end of the body; and drive means for driving a contraction of the bladder, arranged on the dorsal wall and having a mechanical connection with the ventral to cyclically attract the ventral wall to the dorsal wall, thereby causing a pulsed ejection of a propeller jet from the chamber through the outlet opening.
