Microfluidic devices including fluidic multiplexers

A microfluidic device comprising:

• a plurality of fluidic channels;
• a plurality of fluidic micro-valves fluidically coupled to the plurality of fluidic channels;
• a plurality of pairs of control lines that cross the plurality of fluidic channels proximal to the plurality of fluidic micro-valves;
• and
• circuitry coupled to the plurality of pairs of control lines and to address the plurality of pairs of control lines to:
• set a first subset of the plurality of fluidic micro-valves in an open state;
• and
• set a second subset of the plurality of fluidic micro-valves in a closed state, wherein the first subset of the plurality of fluidic micro-valves in the open state and the second subset of the plurality of fluidic micro-valves in the closed state allow flow of fluid through a subset of the plurality of fluidic channels and prevent the flow of fluid through the remaining plurality of fluidic channels.

A method comprising:

• applying a first temperature to a first subset of a plurality of fluidic micro-valves of a microfluidic device, wherein the plurality of fluidic micro-valves are in fluidic communication with a plurality of fluidic channels of the microfluidic device;
• applying a second temperature to a second subset of the plurality of fluidic micro-valves, wherein the second temperature is higher than the first temperature;
• and
• in response to applying the first temperature and the second temperature, flowing fluid through one of the plurality of fluidic channels and preventing flow of fluid through the remaining plurality of fluidic channels.
