Abstract
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.
