  • Micromembrane Pumping Device
    Publication number: 20250369433
    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 influe

  • CONCEPT FOR DETERMINING EXTERNAL INFLUENCING FACTORS ON THE BASIS OF THE CONTROL SIGNAL OF A MICROFLUIDIC COMPONENT
    Publication number: 20240335833
    Abstract: The inventive concept described herein concerns a microfluidic component, comprising a membrane actuator with a membrane element and an actuator element for deflecting the membrane element. A signal generation device is configured to generate an electric control signal having a time-variant signal curve for controlling the membrane actuator, by which the actuator element actuates the membrane element. A signal processing device is configured to detect, during operation of the microfluidic component, an influence on the temporal signal curve of the control signal, caused by one or more external influencing factors, and, on the basis of this influence on the temporal signal curve, to identify and/or classify at least one causal external influencing factor.
