Abstract

A fluid device with a fluid chamber, the fluid device including a fluid chamber which is designed for receiving a fluid and which is commonly delimited by a device housing and a bending-elastic membrane element. The membrane element is fixed with a peripheral edge region to the device housing, wherein a membrane working section of the membrane element which is framed by the peripheral edge region can be deflected by a piezoactuator whilst carrying out a stroke movement, in order to change the volume of the fluid chamber. The membrane element is a functional constituent of the piezoactuator by way of it directly forming an electrically conductive electrode of the electrode arrangement of the piezoactuator.
