1. A peristaltic microfluidic pump comprising:
- a pumping chamber positioned between an inlet and an outlet;
a plurality of moveable fingers positioned in a wall of said pumping chamber, said fingers being arranged in a row along said wall; and
a plurality of thermal bend actuators, each actuator being associated with a respective finger such that actuation of said thermal bend actuator causes movement of said respective finger into said pumping chamber,wherein said pump is configured to provide a peristaltic pumping action in said pumping chamber via movement of said fingers.
