Abstract
An apparatus for the conversion of pressure fluctuations prevailing in fluid systems into electrical energy includes in a casing (1) a first chamber (4) which may be connected to a fluid system and is limited on one side by a movable wall, for example a membrane (3). The movable wall is mechanically linked to an apparatus (6), e.g. a piezoelectric converter, which converts the mechanical energy made available by the motion of the movable wall (3) into electrical energy (FIG. 1).
