Abstract
A peristaltic microfluidic pump. The pump comprises a pumping chamber positioned between an inlet and an outlet; a plurality of moveable fingers positioned in a wall of the pumping chamber, the fingers being arranged in a row along the wall; and a plurality of thermal bend actuators. Each actuator is associated with a respective finger such that actuation of the thermal bend actuator causes movement of the respective finger into the pumping chamber. The pump is configured to provide a peristaltic pumping action in the pumping chamber via movement of the fingers.
