Microfluidic large scale integration
First Claim
1. A microfluidic device comprising:
- a microfluidic flow channel formed in a first layer;
a first microfluidic control channel formed in a second layer adjacent to the first layer, the first microfluidic control channel separated from the microfluidic flow channel by a first deflectable membrane integral with the first layer or the second layer; and
a second microfluidic control channel adjacent to the first microfluidic control channel and separated from the first microfluidic control channel by a second deflectable membrane.

Abstract
High-density microfluidic chips contain plumbing networks with thousands of micromechanical valves and hundreds of individually addressable chambers. These fluidic devices are analogous to electronic integrated circuits fabricated using large scale integration (LSI). A component of these networks is the fluidic multiplexor, which is a combinatorial array of binary valve patterns that exponentially increases the processing power of a network by allowing complex fluid manipulations with a minimal number of inputs. These integrated microfluidic networks can be used to construct a variety of highly complex microfluidic devices, for example the microfluidic analog of a comparator array, and a microfluidic memory storage device resembling electronic random access memories.
