The invention concerns a micro-muscle designed to be immersed in a biological liquid, comprising a deformable chamber whereof one portion at least consists of a semipermeable membrane, said chamber containing a solution capable of osmotic activity. The solution is preferably activated by a product to be injected into the biological liquid.

Micro-muscle in biological medium

An actuator for arrangement in contact with a biological solvent includes a housing with a wall which is permeable to the solvent and not permeable to a first solute and which contains micro-organisms for transforming a second solute into the first solute. The actuator further includes a deformable chamber connected to the housing which can increase in volume due to the solvent entering the housing by osmosis. An engine may make use of the actuator.
