1. Pressure Actuated Valve Test Design
Objective
Integrate an active control element into a basic microfluidic design
Utilize preexisting packaging as a template for the design
Concept of Design
Gas lines under thin flexible PDMS layers
At initial pressure, flow is blocked by small gate
Removal of gas causes flexing down of PDMS
Opens line for fluid flow under gate
Add valve figure

2. Pressure Actuated Valve Test Design
Device Logic
Based on Stage 2 Design
Uses T-section to test if directional flow can be obtained
Additional line with two gates across top layer show if gates are a source of leakage or backflow
Bryce figure for reference
