Abstract
A micro-fluidic pump comprises one or more channels having an array of resistive heaters, an inlet, outlet and a substrate as a heat sink and a means of cooling the device. The pump is operated with a fire-to-fire delay and/or a cycle-to-cycle delay to control the pumping rate and minimize heating of liquid inside the pump during its operation.
