1. A micropump for pumping of a fluidic media, the micropump comprising:
- at least one flow duct having at least one wall body;
at least one pinch region in the at least one flow duct; and
at least one actuator, wherein the at least one actuator is capable of exerting force in the at least one pinch region such that a cross-sectional area of the at least one flow duct being capable of being varied in the at least one pinch regions by the force exerted by the at least one actuator.

Abstract
The present invention generally relates to a micropump for the conveyance of fluidic media at low flow rates. The micropump comprises at least one flow duct. The flow duct also has at least three pinch areas. The micropump also includes at least three actuators for the pumping of fluidic media. The actuators are configured and arranged in such a way that a force can be exerted on the flow duct by at least one of the actuators in each of the three pinch regions. This results in the flow duct being narrowed or completely closed at the pinched points and the fluid which is located in this region is completely or partially displaced from this pinched region.
