MICROFLUIDIC DEVICES HAVING A REDUCED NUMBER OF INPUT AND OUTPUT CONNECTIONS
First Claim
1. A microfluidic device comprising:
- a substrate comprising;
a valve;
a reaction chamber;
a first group of independently controllable components, wherein the first group of independently controllable components comprises a first heater configured to heat a portion of the valve, wherein the first group is electrically connected to a first lead;
a second group of independently controllable components, wherein the second group of independently controllable components comprises a second heater configured to heat a portion of the reaction chamber, wherein the second group is electrically connected to a second lead;
a third group of independently controllable components, wherein the third group of independently controllable components comprises the first heater and the second heater, and wherein the third group is electrically connected to a third lead; and
wherein the first heater is independently controllable via a combination of the first lead and the third lead, and the second heater is independently controllable via a combination of the second lead and the third lead.

Abstract
Provided herein are systems and methods for reducing the number of input/output connections required to connect a microfluidic substrate to an external controller for controlling the substrate. For example, provided herein is a device with three groups of independently controllable components, where the first group includes a first lead and a first heater configured to heat a valve; where the second group includes a second lead and a second heater configured to heat a reaction chamber; where the third group includes a third lead and the first and second heaters; and where the first heater is independently controllable via a combination of the first lead and the third lead, and the second heater is independently controllable via a combination of the second lead and the third lead.
