2. Problem Definition Motivation Goal
BioMEMS research is growing rapidly, but restricted to single layer microfluidics
Development of a multilayer microfluidic design would increase flexibility
Goal
Design, construct, and test a controllable microfluidic device with at least two fluid levels.
Identify appropriate materials, processes, and device geometries.
Add pictures. Show old and new. (Dan)

3. Problem Scope Requirements Constraints
To make a two-level microfluidic device
To incorporate active control elements
Constraints
Assume external fluid control
Neglect biochemical reactions in channels
Keep design feasible for manufacturing

4. Initial Material Choices
Narrowing Materials Choices
Desired Mechanical and electrical properties
Process considerations
Create materials table: rigid SU8, flexible PDMS, Pyrex and silicon as substrates. (Anne, Charles)
