Abstract
What is suggested is a micromembrane pumping device for pumping a fluid, having: a pump chamber to which an inlet valve, an outlet valve, and a membrane device for varying a volume of the pump chamber are associated, wherein the membrane device has a plate-shaped actuator for deforming the membrane device; and influencing means for influencing the plate-shaped actuator and the volume of the pump chamber; wherein the membrane device has a plate-shaped membrane body limiting the pump chamber; wherein the plate-shaped actuator is arranged on a side of the plate-shaped membrane body facing away from the pump chamber; wherein the plate-shaped actuator is mounted to and electrically insulated from the plate-shaped membrane body by an electrically insulating glue layer; wherein at least one embedded portion of a support body at or in which a deformation sensor for detecting a deformation of the membrane device is arranged, is arranged within the glue layer to detect the volume of the pump chamber; wherein the influencing means, the plate-shaped actuator and the deformation sensor form a closed-loop control circuit for regulating a volume flow.
