Electrostatic pump

A microfluidic pumping system for providing continuous or pulsed pumping action of a sample fluid along a microfluidic channel (301, 401) of a microfluidic device is described. The pumping system comprises at least one actuator (405) comprising an actuator channel (305) and polarizing means (306) for generating pumping fluid motion, and at least one microfluidic rectification system (304, 310, 402, 403) for facilitating the flow of a sample fluid in a predetermined direction, the at least one microfluidic rectification system (304, 310, 402, 403) being laid out in or along the microfluidic channel, and the at least one actuator (405) being adapted for creating a pressure in the microfluidic channel, the system thus being adapted for providing continuous or pulsed fluid movement of the sample fluid along the microfluidic channel when actuation of the pumping fluid in the actuator channel takes place and further providing sample fluid immobilization when no actuation takes place.
