Title
(DE) OSMOTISCHE PUMPE MIT MINDESTENS EINEM AUFLADBAREN MATERIAL
(EN) OSMOTIC PUMP WITH AT LEAST ONE CHARGEABLE MATERIAL
(FR) POMPE OSMOTIQUE COMPRENANT AU MOINS UN MATÉRIAU À CHARGER
Abstract
(EN) The invention relates to an osmotic pump (1) comprising at least one chargeable material (30) whereby the osmotic pressure is caused by inducing and/or de- inducing charges within the material.
(FR) L'invention concerne une pompe osmotique (1) comprenant au moins un matériau à charger (30), la pression osmotique étant réalisée par la création et/ou la destruction de charges dans le matériau.
