1. A microfluidic system for processing microfluidic samples, comprising:

  • a substrate defining a microfluidic network comprising at least one thermally actuated valve and at least one thermally actuated pump configured to manipulate microfluidic samples within the device;

    a plurality N of independently controllable heat sources, each heat source having at least two terminals, at least one of the heat sources is configured to actuate the at least one valve, at least one heat source is configured to actuate the at least one pump;

    a plurality of input/output contacts for electrically connecting the terminals of the heat sources to a controller, wherein the number of contacts required to independently control the N heat sources is substantially less than the total number of terminals.
